Pipecolic acid (piperidine-2-carboxylic acid) is a small organic molecule which accumulates in pipecolic acidemia. It is a carboxylic acid of piperidine.

Biochemical effects[edit]

Pipecolic acid can be associated with some forms of epilepsy.[1]

CRYM, a taxon-specific crystallin protein that also binds thyroid hormones, is involved in the pipecolic acid pathway.

Environmental abundance and relevance[edit]

Pipecolic acid was identified in the Murchison meteorite.[2] It also occurs in the leaves of the genus Myroxylon, a tree from South America.[3]

Stereochemistry[edit]

Pipecolic acid, like many other α-amino acids, has a chiral stereocenter at the α carbon.
