    - for Alanine you put the beta-alanine structure (you meant to put alpha-alanine)
    - the structures of methionine and leucine are inversed

    9:22 ....I have question ..as u have said the alpha helix ends are slightly polar so they are neutralized by negatively charged group on N terminal end and positively charged group on C terminal end so I have to ask do alpha helices always end with *Lys* or *Arg* in C terminal end? I mean lysine or arginine is used to neutralize it to attain stability so would there always be Lys or Arg at that end?

      not necessary ...we cant imagine alpha helix as a isolated entity ....in a protein there could be a long peptide chain and some part might take a conformation of alpha helix and some other part may take a conformation of beta pleated sheet....keep on watching this video series....things would be clear

    Hi!
    is there a specific order for amino acids to be able to form an alpha helix? for exempel i had an exam question where they asked “ will this order of amino acid sequences form an alphab helix?” and the right answer were “no because every third amino acid is positive charged”

    • @animatedbiologywitharpan
      @animatedbiologywitharpan  3 роки тому +2

      Different amino-acid sequences have different propensities for forming α-helical structure. Methionine, alanine, leucine, glutamate, and lysine uncharged ("MALEK" in the amino-acid 1-letter codes) all have especially high helix-forming propensities, whereas proline and glycine have poor helix-forming propensities. Proline either breaks or kinks a helix, both because it cannot donate an amide hydrogen bond (having no amide hydrogen), and also because its sidechain interferes sterically with the backbone of the preceding turn - inside a helix, this forces a bend of about 30° in the helix's axis. However, proline is often seen as the first residue of a helix, it is presumed due to its structural rigidity. At the other extreme, glycine also tends to disrupt helices because its high conformational flexibility makes it entropically expensive to adopt the relatively constrained α-helical structure.

    just a small concern on the material of this video. H-bonding between alpha C and N in the backbone isn't it between 1st C and 4th N (n+3 not n+4).

    • @animatedbiologywitharpan
      @animatedbiologywitharpan  4 роки тому +8

      No I am totally confident about the material .please refer to the following point.
      in alpha 3.6 (13 ) helix every mainchain C=O and N-H group is hydrogen-bonded to a peptide bond 4 residues away (ie O(i) to N(i+4)). This gives a very regular, stable arrangement.
      In contrast to 3.6(13 ) helix the 3(10) helix has a different pattern.Here the main chain hydrogen bonds are between residues separated by three residues along the chain (ie O(i) to N(i+3)).
