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!
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.
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 👍🏼
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
This is highlu relevant. Please also post a video on complete review of all biologically important micromulucles - nucleic acid, amino acids, carbs and glucose.
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.
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
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 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!!!
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 😅⭐
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!
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.
OK wow. I just watched this video once. And I'm already doing way better on amino acid questions. Thank you for a very helpful video! Fingers crossed I ace the MCAT lol

you misspelled Tryptophan
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
u a real homie for sharing this!

The timing of this video is gold!
That's strange, he's timing is always on point xD
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.
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.
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 👍🏼
You Rock - I'm going to ACE THE MCAT!
Good luck!!! (:
Lewis Johnson how did u do?
how did you do!?
@@luvibraswell4162 Unfortunately he died taking the MCAT
I hope you did and get into medical school!
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. :)
Hey a fellow Fire Emblem fan who’s also doing medicine :)
How was med school?
@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. 🥰

This has been a great help for my Protein Chemistry mid-term. Thanks a million!
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?
I am preparing my cell biology and biochemistry for the new semester, this video is fantastic! Thank you so much!
How old are you
its nice knowing that people study in the holidays so i dont feel left out at my uni or in my class studying in the holidays is like you are a joke

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
You the best thing that haS ever happened to my studies...keep up the good work
This was AMAZING! I am a first quarter Chiropractic student and Biochemistry will be much easier because of you! LOL. Thanks!
The best teacher ever ❤😊
Thank you very much
Literally saved me for biochem THANK YOU

theres nobody in the world i appreciate more than you and your videos
Thanks so much ,I really benefited. I hope everyone here benefited as well
The best lecture on topic I’ve heard.
YOU THE ONLY ONE I TRUST ON MY STUDIES
You saved my life thank you so so much 💛😭
kinda mine too xD
me too :)
As a pharmay student, THANK YOU SO MUCH! ❤
You're the only reason I have passed any of my science or math classes. Thank you so much
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!!!
Why are your exams only worth 20 points lol.
@@freddymendoza9393 The exams are normally like 70 - 80 points and then it's got set back to 20
Organic Chemistry Tutor, I hope you know I love you.
Thanks a lot. It helped me memorizing it. Love the way you teach!
My Histology course just started and this was the 1st requirement But you put this video a month ago....thanks bruh
شكرا جزيلا

for the A.A. that have polar and non-polar properties, they are referred to as amphipathic
Love from Bangladesh 🇧🇩 💞.
Thank You so much Sir ❤️.
This video is very helpful to us ❣️
I just Love it 😍.
Im korean, I really thanks for your lecture.
감사합니다.
Nice.
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 😅⭐
Able to memorize all property in 1 day. Thank you my good sir
Well put together. I certainly can memorize them now. Thanks a lot
Thank you sir this video has been really very helpful .keep making such videos
your are the best youtube teacher ever! thanks
yes yes yes got this just in time for my exams thank you
Thank you 🙏 for this video, you're highly appreciated 👍 may our loving father God bless the works of your hands sir 🙏🤗 thanks once more
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!
This is helping us the biochemistry students
grateful here.still useful content even now
Does arginine have 2 NH2 groups at the end? It’s not HN=C(NH2)-NH-(CH2)3-CH(NH2)-COOH ?
it was the easiest way to remember thanx a lot
THANK YOU. PERFECT TIMING
Heavenly sent lesson. I really enjoyed it.Post more videos on other micromolecules
thank you so much, it really made understanding the structures easy
Thanks so much just what I need at the right time😊😊🙏🙏
Thank you for making things much easier
We appreciate it
I OWE MY LYF TO U MAN! ❤️❤️❤️
Incredible video like all your videos , I can imagine how they helped me .it is like impossible .
Thank you .
Excellent and easy to understand, Thank you so so
much
Thankyou so much for making it so simple for me to understand
Now I understand the value of my NCERT books
😢 have any advice for a 12th std student?
Thank you very much.I love your video❤
Thank you so mush 😭👏🏻👏🏻
You make it easier for me 😭💗💗
Was Very helpful! Thank you 💕
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.
Thank you so much. It really was, is and will be useful to me and everyone I guess 😊
I love your contents ❤❤
Why doesnt the coo- and nh3+ make the compound polar as well?
Thank you... I am a big believer in drawing and modeling too
The best movie of the year🎉❤❤❤❤❤❤❤❤❤❤❤❤💯💯
Knowing the Origins can help see things more clear.
perfectly explained! thank you
Wow! This is so helpful, thank you
Such a lifesaver as usual
Thank you so much for this!!!
You are amazing man.
OK wow. I just watched this video once. And I'm already doing way better on amino acid questions. Thank you for a very helpful video! Fingers crossed I ace the MCAT lol
i am also korean and i understand write type speak english but also korean i learned all the amino acids because u thx
Thank you so much, very very helpful
thank you for the video!
Thank you sir ,it's really helpful to me
At this point I should really just give this guy all my tuition money
Can you you upload some biochemistry lesson like proteins
Please does anyone have a link to find out how we manufacture amino acids? , as in food supplements. Many thanks.
why is it NH3 when i draw it is only two hydrogens? Im really confused.
amino acids exist as zwitter ions i.e. have both nh2 and cooh groups ionised, thats why
Is a Zwitterion
Depends on the pH of the solution
Thank you so much i was struggling now im fine💟
Thank you sir 😁😄❤️✨
Nice review! Thank you for sharing!
