Question

Quizplus · Accepted Answer

Hydrogen bonds stabilize the alpha helix and beta pleated sheet structures of proteins. In the alpha helix, hydrogen bonds form between the carbonyl group of one amino acid and the amino group of another, stabilizing the helix shape. In the beta sheet, hydrogen bonds form between chains of amino acids that are adjacent but not necessarily close together in the primary sequence, stabilizing the pleated sheet shape.
