Question

Helical segments of protein molecules arise through hydrogen bonding between C  O and N  H groups.

Quizplus · Accepted Answer

This is true. Helical segments of proteins are stabilized by hydrogen bonding between the carbonyl oxygen (C=O) of one amino acid and the amino hydrogen (N-H) of another amino acid, located four residues away. This hydrogen bonding pattern gives rise to the characteristic alpha-helix secondary structure in proteins.
