Quizplus · Accepted Answer

Hydroxylysine and hydroxyproline are both unique amino acids found in collagen, a fibrous protein that provides structural support in the connective tissues of the body. Actin is a globular protein responsible for muscle contraction, fibrinogen is a soluble protein involved in blood clotting, and hemoglobin is a protein that carries oxygen in red blood cells. None of these proteins contain significant amounts of hydroxylysine or hydroxyproline.
