Since they are located on the exterior of the αlpha-helix, R groups do not affect helix stability.
a. True
b. False
Homework Answers
b) False.
The two factors which determines the stability of the alpha helix are following:
* Steric hinderances: The presence of R chain on the exterior side in the alpha helix reeuce the steric hinderances in aloha helix. In this way, it determines the stability of the alpha helix.
* Hydrogen bond: The presence of hydrogen bond stabilises the alpha helix
That's why statement is false. Because side chain determines the alpha helix stability.

Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids
Distinguish between the different levels of protein structure, including primary, secondary, tertiary, and quaternary Question Is the following statement true? If not, explain why not: Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids (a hydrogen on an amide N on one amino acid interacts with an oxygen on the carbonyl of another amino acid), the secondary structure does not depend on the specific amino acid groups (the R-groups) in the amino acid chain. Select...
