title: A case of an exceptionally high level of urinary-4-hydroxyproline containing polypeptides.
abstract: The determination of total urinary-4-hydroxyproline in an adolescent showed a very high excretion of hydroxyproline containing peptides: 26.2 mmol/24 h. Estimation of total urinary 3-hydroxyproline and peptide fractionation on Biogel P 2 demonstrated unusual features. Such cases are of great interest for structural studies of the urinary polypeptides and understanding of collagen catabolism.
