| pterosauria | <paleontology> An extinct order of flying reptiles of the Mesozoic age; the pterodactyls. Synonym: Pterodactyli, and Ornithosauria. The wings were formed, like those of bats, by a leathery expansion of the skin, principally supported by the greatly enlarged outer or " little" fingers of the hands. The American Cretaceous pterodactyls had no teeth. See: Pteranodontia, and Pterodactyl. Source: Websters Dictionary (01 Mar 1998) |

| pteroyl polyglutamate hydrolase | <enzyme> Catalyses the hydrolysis of pteroylpolyglutamic acids in gamma linkage to pterolylmonoglutamic acid and free glutamic acid. Registry number: EC 3.4.22.12 (12 Dec 1998) |
| pteroylmonoglutamic acid | <biochemistry> Pteridine derivative that is abundant in liver and green plants and is a growth factor for some bacteria. The biochemically active form is tetrahydrofolate (see folate). (12 Nov 1997) |

| 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.

| pterin |
the 2-amino, 4-hydroxy derivative of pteridine; the term is also used to denote the class of compounds containing such a ring structure, such as tetrahydrobiopterin or folic acid. Pterins are so named because they were first identified in the wings of butterflies.
