    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 UA-cam it isn't because I'm itching for a good read.

    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.

    • @fishcious
      @fishcious 2 роки тому +3

      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.

    @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
      @ProfessorDaveExplains  4 роки тому +2

      the carboxyl must also remain protonated, but the amino group being protonated is what gives it the positive charge

      @luvisacigarette8 4 роки тому +1

      @@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?

      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.

    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.
