Pipecolic acid

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

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.

Pipecolic acid was identified in the Murchison meteorite.
