In an Alpha Helix, the Coiling Is Stabilized by

Multiple Choice

In an alpha helix, the coiling is stabilized by

A) the hydrophobic nature of the R chains, which causes the chain to coil with the R groups inward.
B) hydrogen bonding of the N-H groups on one amino acid and the C=O groups on another.
C) repulsion of the R chains from each other, causing the coil to form with the R groups on the outside.
D) disulfide bond formation between cysteines that are regularly spaced along peptide chains.
E) the N-C-C repeat of the peptide backbone, allowing for regularly spaced peptide bonds between chain segments.
