I'm a undergraduate in Japan. Your English is easy to catch and recognize. The flow of this video is easy to understand. I thank you to create such a good video. I am looking forward to see your next video.
Wow. Please change your name to “Professor Dave Saves the Day”. This will be the third class you’ve helped me study for. I don’t know what is about your videos, but they are seriously incredible for an advanced student with ADHD. I always brag on them and share them with peers.
Thank you for making a video where you SPEAK on a subject that I searched for. So many videos on amino acids are just musical power points with no narration. I don't want to sound like a dumb tool, but when I visit TH-cam it isn't because I'm itching for a good read. Much appreciated!
Professor Dave is the only person who can explain a topic with deep information and never stop us from learning.. Sir really thanks ur patience and best explanation...
Thank you teacher... i have always been concerned about chemistry and biochemistry but now with this lectures i hope to understand them better... please keep uploading this kind of videos you make a difference in our life.. !!
Thank u professor ❤️.. I have small problem.. I can't get understanding all the vid because I don't speak English very will.. I need Arabic translation please ❤️.. I understand 75%..
I didn't know any of this stuff, I take L-Phenylalanine, L-Arginine, L Ornithine and L- Lycine with Niacin, C and glycine and sometimes I do take them with a tall glass of apple cider vinager and water. Now I have to re learn everything I thought I knew. Thank you so much. I very rarely eat meats so I take these and they energize me is the main reason I take them. They also help me to think. I do drink two glasses of the acv mix so my system stays non acidic or so I thought. Thank you, again.
So we have this huuuge chemistry exam we have to pass to be accepted for further medical school and without Professor Dave I would not be on my way to become a doctor anymore haha :D Thank you so so so much!
Every time I want to learn something I fall into these endless rabbit holes. I just wanted to know what a protein is and what a vitamin does. I still don't, but now I'm aware that I also don't understand what an enzyme is, what carbohydrates are, or amino acids, genes, DNA, RNA, organic compounds, the inner works of cells. Man... I need a few dozen lives just to grasp the slightest nip.
I was wondering why Nitrogen in the amino group has a lone pair which makes it basic. Thinking that it makes the amino acid unstable. Thank you Professor Dave, for explaining that that's how amino acids react.
Nitrogen has 4 orbitals and 5 electrons in its valence shell. Since each orbital can hold at max 2 electrons, N has one full orbital and 3 orbitals w/ 1 electron each (these are the ones that make bonds so that N 'feels like' it has a full (8 electrons) valence shell. The orbital that is already full is that lone pair and since it has a partial negative charge, that makes it slightly basic because that partial negative charge can attract and hold onto a positive H+ ion.
Your are really good in teaching We small small students need u very much Plz cover whole topic in detail so that we have a deep knowledge of the topics
@3:14 there's a switch in the amino group of the zwitterion (H2N to H3N). In this sense, the cationic form should be understood as when the carboxyl group being protonated [as opposed to what was said @3:03]. Is this accurate?
@@ProfessorDaveExplains Thanks for the prompt response. Quick follow up: if the *amino group* being protonated is what gives it the positive charge, why is it that the difference between the cationic and the zwitterionic forms is found in the carboxyl group (COO- in zwitterion to COOH in cation)? Wouldn't the tacked on proton to the carboxyl group be the main factor yielding the positive charge?
Hey i study in pharmacy college and now i am in 3rd stage, i am sure that when i finish pharmacy and get graduated if someone asked me what did you learn in college i will definitely say “He knows a lot about science staff with professor Dave Explains. Haha thank you so much.
At the end of the video, how was alanine protonized AND deprotonized at the same time? Right before that Professor Dave said it could be either of the two states depending on the pH of the environment.
Thank you for explaining some difficult concepts. If only I had these videos back in the day. These kids these days have it so easy with the internet man. To everyone reading this: God loves you and has a unique purpose for your life!
The substitution of a single amino acid in a cell receptor might have a significant effect on the receptor's structure and function. Can you explain an example. How about disease were a receptor is affected?
well acids protonate things, so if there's lots of acid around, it will protonate whatever's in there. bases deprotonate things, so with lots of base, everything in there is deprotonated.
@@ProfessorDaveExplains alright so basically in an acidic solution the zwitterionic form of amino acids gets protonated, leading to the formation of the cationic form, hence the acidic sol favoring the cationic form.
Would an acidic solution not favour the anionic form? Since the excess protons in the acid will then be able to neutralize the anion. Great video by the way!!
1:06 what this 'standard block' they all have is named? I can find the 20 amino acid names quiet easily on the internet, but doesnt this base block have a name itself????
Haha all those students like me out there.... isn't it amazing. Sometimes it is just so difficult to even try to understand what the teacher is saying in class. Then we'd be rushing around TH-cam looking for saints like P.Dave
@professordave I've looked on your page but can't seem to find it. Do you/could you do a video specifically on pH & Amino acids? Protonation vs. deprotonation when looking at pH of solution and pKa of the functional group etc. ie. To determine the structure or charge of any amino acid: • If the pH of the solution is LOWER than the pKa of the functional group, the functional group will be protonated. • If the pH of the solution is HIGHER than the pKa of the functional group, the functional group will be deprotonated.

I had just three days to study for an exam for a semester and I told a friend that it would only take a miracle for me to pass he then told me to search for Prof Dave on TH-cam that I'll see Jesus performing miracle and after watching your videos things I couldn't understand for weeks become clear in minutes it really a miracle 😁

god sent jesus to earth to teach us some chemistry
uhh no
There’s something MORE dense than a glacier, it’s your head
LOL, That was a good one! ^_^
That is, because god is a chemisist. He made us of amino acids in a lab called:
Show more.
no. He sent Jesus on earth to die for our sins.

Would an acidic solution not favour the anionic form? Since the excess protons in the acid will then be able to neutralize the anion. Great video by the way!!
but acids protonate things! so any basic functional groups will be protonated by an acid, and you get the cationic form.
