Introduction to amino acids | Macromolecules | Biology | Khan Academy

[@tadelli11]

i study biology and your videos have the best explanations ive seen so far. keep it up!

[@MrKillershade]

Good video overall, but serine has only one CH2 in their R group.

[@cipensagiada2667]

SER is errated. The R group is actually CH2OH :)

[@RonnieTeeSmith]

CiPensaGiada you're right, there's an extra methylene group (CH2)

HOW IT CAN BE LIKE THAT I CANT UNDERSTAND WHAT U GUYS ARE SAYING

[@sahilbhat4454]

I'm really very weak in biochemistry..... Kindly help me...

[@dimlighty]

@@sahilbhat4454 How do you feel about biochemistry now?

[@phonetutor]

Such a great teaching voice.

[@swivarithanlgooding-splatt7426]

Creepy

[@katrinaxcx]

Very helpful, thank you!

[@iMusikkForeva]

Two biology classes/professors later I finally understand all of this clearly. But it was thanks to your video!

[@AndersErichsen-rr7vs]

What is the program used for this presentation?

[@jackgrothaus2722]

I love watching Khan (Khan) Academy (Academy) videos!

[@Hollohon]

Jack Grothaus boo

[@anniewang9937]

Very well explained!! A fantastic lesson achieved. Just one question teacher, it is a multiple choice in exam that says either amino acid is converted to glycogen to be used in respiration or amino acid is converted to both urea and glycogen?

[@zahhio8000]

Can we have a bond between polar and nonpolar side chain ??

[@danthadon87]

Illustrations are far superior when it comes to comprehension for the laymen especially for content as complex as this.

[@hz6612]

Your explanation is 5/10 ..

[@shannonduncan8374]

amino acids glutamic acid, aspartic acid, histidine, lysine and arginine. Why do these amino acids play an important role in the tertiary structure of proteins?

[@yanzhangluo852]

Shannon Duncan They can undergo electrosteric interactions.

[@shawnjung6799]

They make proteins by ribosomic transcription and a bunch of other stuff happened

[@VernonChitlen]

DNA doesn't replicate itself. It is code, information. A helicase divides the dna and enzymes prevent the mRNA from tangling and the protein formation for the replication are formed by ribosomes, very complex macro molecular machines.

amazing work .. thanx 😃

[@louerleseigneur4532]

Thanks a lot sir

[@irazani97]

amazing work ☺💔. i lovvvee itt ♡¡!

[@daserstereichen]

Does the protein function comes from its shape solely ?

[@frapocappochino]

IAMTHEO the 'shape' of a molecule does not determine its function, the represented shape is just a graphic example

Hayaan mo sila

[@wildzubatappeared]

I watch it for fun

[@wildzubatappeared]

Central Dogma 😘

[@killteam26]

If the R chain is hidrofilic because the variance of electonegativity between the oxygen and the hydrogen; it means that the carboxyl group is also hidrofilic?

[@Hollohon]

That burp at the end caught me by surprise

[@scarpos7483]

do you have videos about , catabolism of amino acid ?? the aminotransferase ,!

[@nethmamadawala8447]

I'm only 13 why am I forced to learn this

[@onethdasanayake3689]

Follow your dreams dude, if this is useless for you, I agree, just do what you love.

[@nethmamadawala8447]

Yah but doing what I love is singing and it’s not a stable path in the country I live in

[@onethdasanayake3689]

@@nethmamadawala8447 are you from Sri Lanka? (I'm from Sri Lanka btw)

[@nethmamadawala8447]

Yes I’m from Sri lanka

Why live or nature use only left amino acides to construct DNA

[@yves_jotres]

how amino acids and dna form in nature?

[@Monstero5o]

yves jotres only god knows that

[@yves_jotres]

@@Monstero5o nvm I read a book about it, its explained well

[@brittlov279]

I HAVE A QUESTION WHERE ARE THE AMINO ACIDS FOUND IN DNA

[@hauo4783]

I think amino acid is not found in DNA, it is found in cytoplasm where synthesize protein.A simple way eukaryotes In nucleus, DNA to RNA during transcription and in cytoplasm RNA is translated into protein(monomer is amino acid).

[@mizaelreyes7749]

Proton will concentrate the proton at stage 1

This is exactly why PowerPoint was invented. People who can't speak while writing something different. I can't do it either. But I have learned to use the tools appropriate for my skills.

POV: yu saw this in tiktok ✨sal khan✨

[@h.s.hashim5558]

It was help ful but why the is no arabic translate

[@leonardokennedy9948]

I have a question!!
How many are amino acids in kids?

[@brenricaodeji9940]

Idk

[@leonardokennedy9948]

Issac Newton
It’s 19 ,dude

[@leonardokennedy9948]

Issac Newton
Kinds of amino acids , not number

[@leonardokennedy9948]

Bad ! Really bad
