Polypeptide:
Structure and Bond |
|
Definition
[image]
amino acids are linked by covalent, peptide bonds |
|

Reaction Coordinate Diagram:
Spontaneous? |
|
Definition
-No, but the bonds exist because they're kinetically trapped
(high activation energy so spontaneous backward rxn is very slow)

Term
Polypeptide:
Bond flexibility & how it's measures |
|
Definition
φ and ψ are the rotating, moveable angles in the peptide backbone which varies based on R-group
φ-angle between nitrogen and Cα
ψ-angle between carbonyl carbon and Cα
Measured using a Ramachandran plot, where more shading=more flexible/variable=smaller R-group |
|
|
Term
|
Definition
There is a parial double bond between the carboxylic acid carbon and amino group, limiting this bond's flexibility and putting these atoms on the same plane
