Pop quiz: alpha helices are stabilized by hydrogen bonds between the carbonyl group of residues i and the amide group of residues i+4 of the next helical turn. but the first and last turns don’t have a turn before or after them, respectively, which leaves the usual alpha-helical interactions for several residues unfulfilled. based on the hydrogen bonding requirements at the beginning of an alpha helix, which of the following amino acids do you predict is very common just before the start of a helix to stabilize the first helical turn?
a) gly
b) phe
c) ser
d) arg
e) ala
