Description : Hydroxyproline is an imino acid normally present in human plasma. It is derived primarily
from endogenous collagen turnover and the breakdown of dietary collagen. The finding
of elevated (5- to 10-fold increase from the normal of less than 50 micromoles) serum
hydroxyproline is thought to be an inherited defect in the catabolism of hydroxyproline.;
