Memorize The 20 Amino Acids - The Easy Way!

This biochemistry video tutorial explains how to memorize the 20 amino acids - the easy way.

Here is a list of topics:
1. Nonpolar Amino Acids - Glycine, Alanine, Valine, Leucine and Isoleucine
2. Polar Amino Acids - Serine, Threonine, Asparagine, and Glutamine
3. Acidic Amino Acids - Aspartate and Glutamate
4. Basic Amino Acids - Lysine, Arginine, and Histidine
5. Aromatic Amino Acids - Phenylalanine, Tyrosine, and Tryptophan
6. Heterocyclic Amino Acids - Proline
7. Electrically Charged Amino Acids

just wanted to share a way of memorising these amino acids that i found a while ago.

1) first memorise the 5 well known aliphatic amino acids in order of complexity:
Glycine, Alanine, Valine, Leucine and then Isoleucine.
2) now, remember the sequence 4-3-2-1 and observe this sequence down the list in the following:

Lysine= -(CH2)4-NH2
Arginine= -(CH2)3-NH-C(NH2)=NH
Methionine= -(CH2)2-S-CH3
Cysteine= -(CH2)-SH

3) Also, recall the "kinda-alcohol duplicates" of Methionine and Cysteine

Threonine= -CH(OH)-CH3
Serine= -(CH2)-OH

4) now, observe how "A" comes wayy before "G" in english alphabet and how "1" comes before "2"

Aspartic Acid= -(CH2)-COOH
Glutamic Acid= -(CH2)2-COOH
Asparagine= -(CH2)-CONH2
Glutamine= -(CH2)2-CONH2

5) Now, we get down the aromatic amino acids.
-CH2-(C6H5)= Phenyl Alanine
Add an -(OH) group to the para position, and we have =Tyrosine

Now, instead of a benzene ring, attach a -(benzopyrrole) to alanine and,
we have= Tryptophan
If you attach an -(imidazole) to alanine, we get= Histidine

6) The last one is the only secondary amino acid, which is Proline and easy to draw

I just practiced drawing all these structures along you everyday( morning and night) for 4 days and Boom!! now I'm an expert in it

[iMKNYA]

Wow, you are literally the only reason I got an A in Organic 1&2. And now you’re posting Biochem videos, while I’m taking the class.... you are such a blessing!!! Thank you!

[matthewbrennan]

THANK YOU, JUST IN TIME. Could you do a series on biochemistry? You have a talent for teaching science

[shirleyareola]

Im a pharmaceutical sciences student and your videos are my life saver in all my majors ! Like do you have any idea how you help someone reach their dreams 😭😭😭😭 i will owe you forever and when i have enough bucks i'll gladly be a patron 💞

There's no reason to hate chemistry with this channel. Hope you can also tackle courses like pharmacology in the future. I just wanna say I'm so grateful from the bottom of my hypothalamus that I've discovered this channel. Most channels require textbook reading to understand the topic. This channel doesn't require any intensive book reading. The information are so condensed (90% of a particular topic found in a textbook) and the explanations are just RIDICULOUSLY simple like my textbooks say I'm dumb but this channel makes me a genius lol Keep up the great work. If I can subscribe for a thousand times, I wouldn't hesitate to give all that to this channel 🙌

Thank you! I graduated in 1978 and never want to forget what I studied! I wish I had this video back then. Reading "The Gene" by Siddhartha Mukherjee, great book! Learning about the DNA.

Really appreciate the time you took for this video. I'd have liked chemistry a lot more if my teachers explained the same in such a vivid manner.

[phronesisesi]

God bless you
You’ve helped me in my college studies and now I’m studying pharmacy in uni
I still follow your teachings
You are a real gem I do appreciate what you do please keep it up 👍🏼

[musmerized]

Thanks but if I had enough time before the test to draw each Amino Acid multiple times I wouldn’t be looking for an easy way to memorize them on YouTube lol

[pacedelacruz]

Thank you much! You're a natural teacher and your voice is so soothing. I love the way you presented this in logical order.

[Kencan]

This is highlu relevant. Please also post a video on complete review of all biologically important micromulucles - nucleic acid, amino acids, carbs and glucose.

[rawankarim]

I’m in the 2nd year of med school and your videos have been life savers since my 11th grade in high school ❤❤❤ can’t thank you enough

[darrellful]

You Rock - I'm going to ACE THE MCAT!

[praj_]

This has been a great help for my Protein Chemistry mid-term. Thanks a million!

[aa]

I am preparing my cell biology and biochemistry for the new semester, this video is fantastic! Thank you so much!

[MedorraBlue]

This is fantastic, thank you so much! Clear images, excellent explanations, and no crazy gimmicks. I'm writing the MCAT next month and this video has been very helpful. :)

[vikramsohal]

Hey OCT so I just to say like so many others, you're so awesome! You've saved me in organic and physics, I was wondering, do you have any or plan to put up any Biochem videos? I'm starting that this semester in about two weeks
