Biochemie für Mediziner*innen

informative and interesting way of conveying the subject which helps understanding them much easier.

Me encantó como lo ha explicado, paso a paso, de manera detallada y concisa. He aprendido mucho gracias a este video, ¡gracias!

This lesson is explained very well! It's clear to me what Lineweaver-Burk plot means and how enzymes are most efficient when they have high Kcat/low Km

Dr. Ahern is amazing at linking what he's about to teach to previous videos.

The following are the errors in the information you provided: 00:24 The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. 01:15 The structural formula for lactose is C12H22O11. This means that it is a disaccharide made up of two monosaccharides, glucose and galactose. 01:39 Polysaccharides are polymers of monosaccharides, but they do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure. Here is a corrected version of the information you provided: Carbohydrates are molecules whose name literally means hydrates of carbon. This is because monosaccharides, the simplest carbohydrates, have a ratio of one carbon atom to two hydrogen atoms to one oxygen atom, the same as water. The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. Disaccharides are carbohydrates that are made up of two monosaccharides. They are formed by a glycosidic linkage between the two monosaccharides. Disaccharides have the general formula C12H22O11. Examples of disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose). Polysaccharides are carbohydrates that are made up of many monosaccharides. They are formed by glycosidic linkages between the monosaccharides. Polysaccharides have the general formula (C6H10O5)n, where n is the number of monosaccharides in the polysaccharide. Examples of polysaccharides include cellulose, starch, glycogen, and chitin. Polysaccharides do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure.

Simple, not over-complicated and understandable, all great signs of an amazing lecture.

Der Vortrag ist sehr gut verständlich aufgebaut, vorgetragen und gegliedert

it's very easy and simply explained and I loved it It was very helpful

I am appreciative that Dr. Ahern took the time to update his lectures. Shows he cares. Thank you!

Der Kurs fängt gut an aber die Blutgerinnung wird dann leider viel zu kompliziert erklärt. Schade.

Recomendo pra todos que querem saber melhor sob Medina das universidades

All the lectures have been so, so helpful. Thank you so much!

Exakte Beschreibung der Vorgänge, gut erklärt. Trotzdem kurz und Bündig. Angenehmer Vortrag!

just got the structure formation of a f actin support epithelial

Super toll erklärt. Ich hab soviel Freude beim Zuhören. Es wird nie langweilig, die Folien sind prima. Der Dozent ist echt mit dem Herzen dabei, das steckt an. Man kann sich auch einfach ne Menge merken nur durchs Zuhören. Vielen vielen herzlichen Dank. ( Fünf Sterne plus Bienchen )

The lecture breaks it down so simple that it’s easier to understand. There’s still more factors that I’m sure they’ll be discussed in other lectures but it’s perfect to help to create a strong foundation in your knowledge

Dr. Ahem explained a complex concept in a very interesting and simple way. Straight to the point and informative. Thank you

Kurs ersetzt Lehrbuch für das Bestehen der Prüfung nicht. Immunologie sehr gute Darstellung aber überpräsent. Der erste Teil ist verwirrend und unsystematisch. Der letzte Teil hat mir gut gefallen, besonders die MC Fragen am Ende. Technisch funktionierte der Kurs bei mir nicht, ständig begann er mit dem ABO Blutgruppensystem und im Wechsel mit dem Physiologiekurs mit gleichem Immunologieteil war es noch lustiger.

I loved this lecture ´cause dr ahern was so clear and it really helped me understand this topic.

Awesome review , covering all the important concepts with clear explanation

All of the videos on this topic are very good, thank you!! It made me finally understand it. I wish we would have more details on the pathologies related to the Purine and Pyrimidine pathways.

Made something so complex easy. I've always had trouble here.

I loved this lecture! Everything was so well explained: simple, straightforward, and I especially love few external tidbits thrown in such as the meteorite portion. It helps to remember these facts. Thank you!

This lecture was one of my favorites as it made something so confusing perfectly digestible.

Dr. Ahern is a very good lecturer. He explains concepts very clearly.

This lecture provided me with so much clarity. Thank you

He explains on a perfect and short way making it easier to understand

Wonderful, simple and easy-to-understand video. Finally got it

This video has several problems. It does not seem to be a continuation of the previous ones, it has unclear information, the reparation itself is not explained, and the name dropping doesn't help either.

Love this lecture. Dr. Ahern explains much better than my professor.

Thank you so much This video helped me so much en my sesions of study

ok. could use improvement please include that Kinesin and Dynein are ATPases that use energy. also that only Kinesin is displayed here. I was so busy looking for Dynein information, that Kinesin info went out the other ear. This could be better by improving the diagram.

I liked the way the R and T states where explained. It all became very clear

I like that Dr. Ahern's way of presenting the topics is informative and does not make me sleep. Usually, our classes make us feel drowsy because of too much information. It helped me understand the concepts more and I was less distracted.

Thank you Dr. Ahern for this very comprehensive lecture. Going through the biochem book makes this topic very complicated. It is amazing how you can simplify this topic to get to the point and what we actually need to understand.

Beautiful and very good explanation . easy slides. thankyou. study matter also provided

THE TRANSLATION IS NOT CORRECT, THERE IS NO CONSISTENCY IN THE SENTENCES

He is the best here , I swear Idk but I like him

such a hard concept explained so easy and well. such an amazing work sir

what an amazing lecture god bless u sir and i wish to meet u someday

Thank you so much; Nonetheless, i really need to let you know your vocabulary is above my reach

I understand very well, thank you Professor Kevin, these help me a lot

Der Kurs Immunsystem möchte ich euch eindeutig empfehlen, und zwar sowohl für die Vorkliniker, als auch für die Kliniker. Besonders schätze ich den strukturierten Aufbau des Kurses, die vielen kleinen Informationen, die bis in die kleinen Details gehen und vor allem die zahlreiche Illustrationen die dieses komplexe Gebiet der Immunologie auf eine angenehme Weise absorbieren lassen. :) Herzlichen Dank! Es wurde mir schon angekündigt, dass man an einem weiteren Vortrag über COVID aus der Sicht der Immunologie arbeitet! Ich freue mich riesig drauf! Bitte mehr Videos über diese Themen oder aus dem Gebiet. Bitte benachrichtigen Sie mich, wenn neue Vorträge zu dem Thema erscheinen.

Magnificent lecture about polysaccharides and their functions for storage and release

The video highlights the important concepts about the hydrophobic amino acids group

this is amazing thank you , i gained a lot of info about viruses that i have not know before

Kurs wurde ganz toll vorgetragen und hat richtig Spaß gemacht! Der Vortragender ist richtig Klasse! Bitte mehr davon :)

Man kann dem Kurs sehr gut folgen, thematisch strukturiert und sinnvoll gegliedert. Nicht nur kommende Ärzte können hiervon profitieren, sondern auch Gesundheits- und Krankenpfleger.

this video is short and easy to understand. Thanks Teacher

Good explanation. Pretty bad diagram. Animation probably would work better.

First of all, I like the depth of this lecture and Professor Ahern is clearly very knowledgeable and concise on the the topic being discussed. And I also like due to the fact that this video is clearly a high-yield resource which is very helpful for my upcoming medical exam. However, I believe that this could have been better had the previous cycles preceding the formation of OMP explained as well in order for us the students to be able to get the essence of the information better. That's all I have got to say

Excellent Lecture from lecturio; I highly recommended for students from medical school. It is an excellent learning platform.

i enjoyed every second of this video and it opened my mind to study more and become what i have always wanted to be a radiologist

Concise and clear; exactly what I needed for this topic, thank you.

No explanation at all just reading , sorry for that , No interaction

beautifuly explained. thankyou!! Every point in every step was explained nicely.

Sorry, the following videos have the information that I was looking for, sorry again

Amazing way of teaching, compact and efficient. Really good job, keep doing it Mr. Ahern.

Has high yield infos which are not in other lecturer's lectures

I really like the video, makes medical biochemistry easier to understand

I loved it, really interesting and easy to comprehend, thank you very much :)

It almost always fails to explain 'why'. These lists are available in any textbook. I was looking for an explanation to understand it. Also, visually it is looking at a table for 5 minutes, pictures could have explained better.

this presentation was good and the way sir explained the concepts was nice

Great professor and easy biochemistry topics to learn with good explanation.

It is an xcellent explication! I understend it at all. Thank you

The Professor is excellent, every one can understand easily de concepts

Excellent teacher . Great lectures . He knows how to teach the subject matter

two stars just for the effort. But its ore like reading fro book. Nothing different. Very boring. No interaction.

I love it... 100% worth it... Made it simple and easy to understand!

I like Dr. Ahern's lectures, I think he is the best in this program. He's very straight forward, precise, concise and connects different points related to what he's talking. After seen these videos I went ahead and did a q-bank of a different program and nailed the ones related to this thanks to his lecture. Some people need to keep in mind that these lectures are not going to cover every single detail, but unlike lectures from others study courses, they do cover more than the basics. For broader information with specific details you definitely need to read textbooks (e.g. Guyton, Robbins, Harrison's) and " google" it up.

The DNA Repair lecture was not very clear at all.

Thank you for your knowledge and for spreading it in this way for us, the students.

I couldn't follow this lecture - it was not presented well at all.

its good and thorough, also covers minor lipid types! good to learn

Simply explained with a little history that made it fun and also helps keep the connection to the content, So much of medical knowledge is facts and figures which can easily become blurred in my mind. The connection to history helps this content stand out in my head! Thank you!

Explains it completely from the start to the end , everything is clear and simple . The structure is very easy to understand.

Very high-yield. Thank you for underlining this moment, crucial in treating hypercholesterolemia.

I have taken biochem as an undergrad, grad. and post grad and I've never had anyone explain things as clearly. Dr. Ahern is one of the best teachers I've ever encountered. Thank you!

I am a student at Downey High and I really want to be a cardiothoracic surgeon, and I didn't know what to learn but I know this website will help me.

A+ teaching style and delivery thank you Dr Ahern for making a difficult topic easier to digest

I think it is an entertaining way to learn the history of Biochemistry.

The video helped me understanding this topic with visual representation

I love this guy. The way he explains makes Biochem look easier

I loved how I understood the bigger picture in the end of the lecture

he is very clear and is a nice teacher, and he use a appropiated nivel of technicims

I really liked this site ,and it's seems helpful for me . I am a high school student. I am in the 10th grade right now. I just want to become a surgeon doctor because I want to save peoples lives. I know that I have to right a commit to this site and I do not have to introduce myself for you people. I do not need to study this because I did not understand today's subject.I just want to be ready for the medical school. I hope this website will help me being ready and ,Good Luck.

I finally understood why we have Lineweaver Burk Plot and how we read it.

Was very clear just speak very quickly, then I have to repeat the lesson to understand complete anyway its not important, I would like just when speaking about the oncogenes give some examples about the food that causes

extremely helpful when the amino acids are divided in functional relevance.

Perfect way of explaining complex things. This is rarely seen by lecturers. Wow!

herrlich unaufgeregt... für folgende generationen bitte mehr von herrn köhrer!

Attaractively and well explained video of serine protease catalytic mechanism that I have ever seen...Thank you..????

:) Thank you . everything in this lecture is clear. like it very much.

A good introduction. Very schematic and overall easy to learn basics.

This is only the first lecture and the first time I am delving into biochemistry for the first time, so hard to say, but something about Prof. Ahern's manner makes me curious and creates a fine feeling of anticipation. Great for a first lecture.

it was described in a simple and easy way to understand, thank you.

This video did not really show Aspartic Acid or Glutamic Acid?

He very easily simplifies things. So this is why I give him a five star review

Amazing, loved it very much. Easy to follow and clear.

Awesome lecture, awesome proffesor. My teacher spent almost 1 hour explaining that. Thank you Dr. Ahern

Nice succinct intro with basic overview -- key points are highlighted

My name is Barbara, I'm from Colombia and I really like your videos Mr. Kevin, because I think the content is easy to understand.

Very well explained and detailed lecture, but it would be nice for better understanding to have some names and terms (e.g. Ramachandran plot) displayed in the video!

way too fast ????I really wish the teacher would talk slower as now I keep having to pause and rewind etc.

Direct , and easy to follow. The length of the video also helps.

Great professor but unfortunately the details of this lecture are not important for USMLE Step 1

Easy to understand and the explanation are very clear. Thank you very much good job!

THANK YOU Pro Ahern you're amazing! very well explained!

Professor Ahern is a perfect teacher and he makes everything so easy to understand

Needs more details, and take it slower so that we the audience can get a more thorough understanding of the topic (the video really doesnt need to be that short)

I found it really helpful. Your explanations were clear and easy to understand.

Thank you for the video's theses are really helpful. look forward to keep learning.

very nice clear and organized lecture. thank you. it adds alot to my simple knowledge

thanks for teaching me in such a clear, precise, and yet enriching way

Thanks for focusing on the "big picture!" The lecturer at my school bogged us down with the details, so it was hard to take in what the most important steps were

excellent lecture. Cristal clear; not too slow not too fast, smooth transitions and a bright ending

It was very precise and up to the point. The presentation was interesting that triggers to study better .

very good lecture. pretty well organized and instructive. He has a deep knowledge of the material making me to pay special attention to all his lectures.

Very nice and informative lecture, easy to understand and remember

I have followed Dr Ahern through all the basics of biochem lectures and he has never failed to deliver.

Very good lecture, l consider that is one of the most complete themes that l´ve read ...good job.

Brief, understandable, high yield information explained with illustrative slides by Dr. Ahern

Conveyed the process in a short &digestable way.I LIKED THE WAY OF presentation too.

his teaching is clear and it is not allowing me to get even a single doubt

I like the way you link things from one to another. Yuu made these lectures highly appreciated with the concise and comprehensive explanation! Thanks Prof!

It is really helpful. I appreciate your kind efforts. Thanks verh much.

i like your teaching .sir. it helps me to understand the concepts clearly.

Excellent information and explanation, it's helping me a lot. Congrats, lecturio!

He simplified the concepts and illustrated by a very nice way

It is very concise and practical it helps me a lot to understand in an easy way the collagen process.

Care for details and passion/curiosity for knowledge are seen in this lecture. I gained a lot from it.

Very profesional, why is it said that bacterial chromosome has a single origin of replication and eukaryotic multiple origins

Thank you so much Sir for brief description of all topics.

the lectures is shallow; i think that more details are needed. it is ineffectual for the level required from the biochemestry course of the Med University of Florence. cordially gioia

Simplified the lecture in enzymes and i like how everything was explained in a simple but direct way. :)

This lecture was very educational, and well organised, moving from the basics to the complicated topics, explaining every topic step by step.

Explains everything extremely clearly and made all of the processes easy to understand. This was a great lecture series!

The lecture was very intriguing! Dr. Ahern is so well articulated!

the lecture is good it educates on how bichemistry is related to other fields in life

Need more details Need to go slower But overall not bad

It is very clearly and enthusiastically explained. You make Biochem easy to understand.

As a medical student I found this series of lectures on enzymes extremely clarifying. Dr Ahern is a great lecturer. Thank you so much.

The lecturer is very good at getting biochemistry across. Well explained and understandable up and until here.

Professor Dr. Kevin Ahern is very clear in presenting. Love the short but very informative lectures. Would recommend to everyone, those with or without biochemistry understanding. Thank you very much Professor and Thanks to the maker of Lecturio.

Fantastic lecture, just the amount of information I needed to cover and retain the topic.

I understood perfectly the concepts the way he explained them. He makes it ease to grasp

few things are missing like discoiling of histone protien and a sentence is not repeates

Very concisely put, I love the lectures, very helpful indeed. Now all I need to do is work my ass off to get the dollars to pay for this awesome lecture. Thank you Lecturio!

I like the way that the AA are presented by a table between essentiel and non essential. I will use it for my memorizing process.

Great/clear explanation, definitely recommend to students. For those that complained, please describe what's needed to be explained, or just keep your pie hole closed. Being ambiguous is pointless.

l am a pre-med student and after watching this lecture I decided I was definitely subscribing! Everything was explained clearly and I understood the concept completely.

Kevin Ahren explained the part very well. I liked the way he explaining this part. I am from business back ground.

i like this lecture. way of representing and explaining is quiet good.

Very nice but there's some need of detailed explanation and then it would be perfect

Thank you so much Dr Kevin, this lecture series are the best that I have seen so far and explain very well, simple and practical a very complicated topic.

Echt super gemacht, die wichtigsten Informationen sind systematisch geordnet und werden strukturiert erklärt. Man kann sich den Vortrag auch gut auf 1,5-facher Geschwindigkeit anhören, wenn man das Thema nur als Wiederholung auffrischen möchte. Ich bin derzeit Medizinstudentin kurz vor der Biochemie Klausur und kann den Kurs Heilpraktikern(Anwärter), Physiotherapeuten und Medizinstudenten empfehlen.

he is so good ... I am very thankful to you sir !!

it was perfect and describe a part of endocrine system very well.

A great, insightful lecturer. A Prof. at the top of his game. Miss his long hair though (checkout his youtube site)!

Awesome job, I wish you were my teacher at my university! So clear!

It was very clear and explained well- the subject itself is usually hard to explain

Thank you Dr. Kevin Ahern!!! Sometimes you speak so fast, but these time was perfect :)
