Quizplus · Accepted Answer

In a standard alpha-helix, there are 2 hydrogen bonds per amino acid residue formed between the carbonyl oxygen of one amino acid and the amide hydrogen of an amino acid four residues away. These hydrogen bonds contribute to the stability of the helical structure. Additionally, each amino acid in the helix has a dipole moment due to the polarity of the peptide bond, contributing to the overall dipole moment of the helix. Therefore, choice C, 2 hydrogen bonds and 1 dipole moment per amino acid, is the best choice.
