In an$\alpha$ helix, the R groups on the amino acid residues:
A) alternate between the outside and the inside of the helix.
B) are found on the outside of the helix spiral.

D) generate the hydrogen bonds that form the helix.
E) stack within the interior of the helix.

Question

Quizplus · Accepted Answer

In an F1F1F1S1F1F1F10 helix, the R groups on the amino acid residues are found on the outside of the helix spiral. This arrangement allows for maximum hydrogen bonding between the backbone atoms and helps to stabilize the helix. The alternating pattern of the R groups helps to prevent steric clashes and maintains the overall shape of the helix.
