Metabolite Identification
Common NameL-Pipecolic acid
DescriptionL-pipecolic acid is a normal human metabolite present in human blood, where is present as the primary enantiomer of pipecolic acid. L-pipecolic acid is a cyclic imino acid (contains both imino (>C=NH) and carboxyl (-C(=O)-OH) functional groups) produced during the degradation of lysine, accumulates in body fluids of infants with generalized genetic peroxisomal disorders, including Zellweger syndrome (OMIM 214100 ), neonatal adrenoleukodystrophy (OMIM 202370 ), and infantile Refsum disease (OMIM 266510 ). L-pipecolic acid levels are also elevated in patients with chronic liver diseases. L-pipecolic acid is the substrate of delta1-piperideine-2-carboxylate reductase (EC 1.5.1.21) in the pathway of lysine degradation (PMID: 2717271 , 8305590 , 1050990 ).
