Metabolite Identification
Common Name1-Pyrroline-4-hydroxy-2-carboxylate
DescriptionMuch or all of the pyrrole-2-carboxylate (PCA) in human urine may be formed in urine from a labile precursor, presumably delta(1)-pyrroline-4-hydroxy-2-carboxylate. Normal human values for endogenous urinary PCA in 16 individuals averaged 0.51 mumol/day, with a range of 0.20-1.3 mumol and a SD of 0.31 mumol. The probable source of human PCA is free hydroxy-L-proline, as inferred from the high value for PCA in the urine of a subject with hereditary hydroxyprolinemia, and from the threeto eightfold elevation in PCA excretion by two normal subjects after a large oral load of hydroxyl-L-proline.
