| pteroylpolyglutamic acids | 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 synthesised 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. (12 Dec 1998) |
| pteroyltriglutamic acid | Pteroyl-gamma-glutamyl-gamma-glutamylglutamic acid;a folic acid conjugate, a principle chemically similar to folic acid except that it contains three molecules of glutamic acid instead of one, in g linkage. Synonym: fermentation Lactobacillus casei factor, pteroyltriglutamic acid. (05 Mar 2000) |
