Application

L-Pipecolic acid has been used as a standard for the quantification by gas chromatography-mass spectrometry (GC-MS).

Biochem/physiol Actions

L-pipecolic acid is implicated in Zellweger syndrome. Pipecolic acid is also a plant defence metabolite. It is a signaling compound essential for systemic acquired resistance (SAR).
L-Pipecolic acid is a lysine metabolite; defect in its catabolism is involved in hyperpipecolic acidemia, cerebro-hepato-renal syndrome, neonatal onset adrenoleukodystrophy, and infantile Refsum disease.

General description

L-pipecolic acid (piperidine-2-carboxylic acid) is a nitrogen-containing heterocyclic compound. It is an imino acid. Its molecular weight is 129.2.

L-Pipecolic acid oxidation was studied in the rabbit and cynomolgus monkey. Tissue homogenates from both species incubated with L-[2,3,4,5,6-3H]pipecolic acid produced a single radioactive product identified as alpha-aminoadipic acid. In the rabbit, L-pipecolic acid oxidation was greatest in kidney cortex
