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
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!
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.
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 💞
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 👍🏼
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 🙌
This is highlu relevant. Please also post a video on complete review of all biologically important micromulucles - nucleic acid, amino acids, carbs and glucose.
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. :)
@rimrd1342 It's going well! I took some time off to be with my family, but now I'm back and I'm halfway through med school. I'm trying to get matched into pediatrics. 🥰 I'm not sure if you're planning on taking the MCAT soon, but if you are, YOU GOT THIS!!! Practice as much as you can, especially with timed practice tests that simulate the real thing. It's a marathon, not a sprint, so keep that in mind for your studying
So it's not memorising. It's learning. And what happened to the amino group being NH2, and the carboxylic acid group being COOH? You might want to explain why the NH2 is written as NH3+ and why the CA group is written as COO- to ensure your audience understands.
I don't have any biochemistry classes (yet), but this video already helped me learn the amino acids structure and names. I've heard that many biochem students don't know them all 20, so i thought, "How bad could it be?" After this, it was not that bad. (I think im gonna learn more about biochem in this channel than in my future college courses)
Thank you so much for this! I was scratching my head an entire night; the order of the amino acids in my lecture notes are just alphabetical according to the one letter codes which doesn't make any sense for remembering the structures. I love how you ordered them so its easier to remember which ones contain a similar component etc ◡̈
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
In dicember when I graduate i need to know how to send you my thank you letter. Almost all my natural science classes I've studied with you. God bless you man.
All aminoacids are polar: the alfa-aminogroup is the + pole and the alfa-carboxylic group is the - pole: thus a dipole! What is non-polar is the R group, the lateral chain for example the lateral chain of Ala is methyl, so as the difference in electronegativity of C and H is small, and also the symmetry of the radical, it doesn't make a dipole. The student, teachers, professors should always put enphasis that the A.A.'s classification refers to their lateral chain.
Thank u so much sir I just entered 200lvl bch and I founded these structures kind of rigorous but u made it so easy for me may God continue to bless u brother looking forward to getting an A tho 😅⭐
Another observation: the alfa-amino groups of the A.A.'s drawings should begin with the H first and then the N linked to the alfa-carbon. H³N+-C- The way he draws gives to the student a wrong impression.
Nope, that's right. Nitrogen has 5 electrons in its outer shell and it can form 4 covalent bonds. I do however think there would technically be a + on the NH due to the hydrogen bond. I hope that helps!
Hey Just want to say thanks for everything you do. Your vids are amazing! I have watched the organic chemistry video's for my exam and thanks to you I got a 15/20 for the organic chemistry exam! Thanks for the help!!!
I’m going into biochem this semester, and have been putting decent effort into knowing the 20 amino acids... can someone answer if it’ll be beneficial to come in with knowledge about the structures??
Yes! Very much! They are like the letters of the alphabet. To write and read you must know the letters. To understand and to know we'll proteins, you must know the AA structures!

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’m reading your comment and the hypothalamus portion has me ded! Lol
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
What was your SAT score?
Thank you soooooo much! You're a natural teacher and your voice is so soothing. I love the way you presented this in logical order.
This has been a great help for my Protein Chemistry mid-term. Thanks a million!

Thank you very much
theres nobody in the world i appreciate more than you and your videos
The best lecture on topic I’ve heard.
you are really helping papa, i just dont have anything to give, you are my one only lecture am relying on keep it up sir

Is his histidine structure wrong? that one Nitrogen has like 4 bonds (20:43)
Nope, that's right. Nitrogen has 5 electrons in its outer shell and it can form 4 covalent bonds. I do however think there would technically be a + on the NH due to the hydrogen bond. I hope that helps!

Does arginine have 2 NH2 groups at the end? It’s not HN=C(NH2)-NH-(CH2)3-CH(NH2)-COOH ?
Why doesnt the coo- and nh3+ make the compound polar as well?
