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