Description
L-Pipecolinic acid is involved in synaptic transmission in the central nervous system. It is also used as pharmaceutical intermediate. It is a lysine metabolite; defect in its catabolism is involved in hyperpipecolic acidemia, cerebro-hepato-renal syndrome, neonatal onset adrenoleukodystrophy, and infantile Refsum disease. It can be associated with some forms of epilepsy. CRYM, a taxon-specific crystallin protein that also binds thyroid hormones, is involved in the pipecolic acid pathway.
Chemical Properties
white to light yellow crystal powde
Uses
L-Pipecolinic acid is involved in synaptic transmission in the central nervous system. It is also used as pharmaceutical intermediate.
Uses
Pipecolic acid is involved in synaptic transmission in the central nervous system. The l-form occurs in plants.
Definition
ChEBI: A pipecolate that is the conjugate acid of L--pipecolic acid.
General Description
Occurs in seeds, malt, edible mushrooms, fruits, etc.
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).
Purification Methods
It crystallises from water. The (±)-picrate has m 158-159o (from EtOH or C6H6). [Beilstein 22 H 7, 22 III/IV 97, 22/1 V 220.] The R(+)-enantiomer [1723-00-8] has m 277o(dec) and [] D 20 +27o (c 4, H2O), and the S(-)-enantiomer [3105-95-1] has m 277o(dec) and [] D 20 -26o (c 4, H2O).[cf p 603, Beilstein 22 III/IV 96, 22/1 V 220.]
