MeSH definition : Derivatives of folic acid (pteroylglutamic acid). In gamma-glutamyl linkage they are
found in many tissues. They are converted to folic acid by the action of pteroylpolyglutamate
hydrolase or synthesized from folic acid by the action of folate polyglutamate synthetase.
Synthetic pteroylpolyglutamic acids, which are in alpha-glutamyl linkage, are active
in bacterial growth assays.;
