| uroporphyrinogen | See: porphyrinogens. Uroporphyrinogen decarboxylase, an enzyme that participates in haem biosynthesis; it catalyses the decarboxylation of uroporphyrinogen III to produce coproporphyrinogen III; it also acts on uroporphyrinogen I; a deficiency of this enzyme will result in either porphyria cutanea tarda or hepatoerythropoietic porphyria. Uroporphyrinogen III cosynthase, an enzyme in haem biosynthesis that participates in the formation of uroporphyrinogen III; a deficiency of this protein results in congenital erythropoietic porphyria.

| uroporphyrinogen decarboxylase | <enzyme> One of the enzymes active in haem biosynthesis. It catalyses the decarboxylation of uroporphyrinogen III to coproporphyrinogen III by the conversion of four acetic acid groups to four methyl groups. Chemical name: Uroporphyrinogen-III carboxy-lyase Registry number: EC 4.1.1.37 (12 Dec 1998) |
| uroporphyrinogen I synthetase | <enzyme> An enzyme of haem biosynthesis that is defective in the inherited (autosomal dominant) disease, acute intermittent porphyria. UP I is isomerised to UP III by UP III synthetase, defective in the autosomal recessive disease, congenital erythropoietic porphyria. (18 Nov 1997) |
| uroporphyrinogen-III synthase | <enzyme> An enzyme that catalyses the cyclization of hydroxymethylbilane to yield uroporphyrinogen III and water. Chemical name: Hydroxymethylbilane hydro-lyase (cyclizing) Registry number: EC 4.2.1.75 (12 Dec 1998) |
| uroporphyrinogens | Porphyrinogens which are intermediates in haem biosynthesis. They have four acetic acid and four propionic acid side chains attached to the pyrrole rings. Uroporphyrinogen I and III are formed from polypyrryl methane in the presence of uroporphyrinogen III cosynthetase and uroporphyrin I synthetase, respectively. They can yield uroporphyrins by autooxidation or coproporphyrinogens by decarboxylation. (12 Dec 1998) |
| uroporphyrins | Porphyrins with four acetic acid and four propionic acid side chains attached to the pyrrole rings. (12 Dec 1998) |
| uropsammus | Synonym: gravel. 2. Any inorganic or uratic urinary sediment. Synonym: urocheras. Origin: uro-+ G. Psammos, sand (05 Mar 2000) |
| uropterin | A sulfur-containing pteridine derivative isolated from urine. Synonym: uropterin. (05 Mar 2000) |

| uropygial | <anatomy> Of or pertaining to the uropygium, or prominence at the base of the tail feathers, in birds. Uropygial gland, a peculiar sebaceous gland at the base of the tail feathers in most birds. It secretes an oily fluid which is spread over the feathers by preening. See: Uropygium. Source: Websters Dictionary (01 Mar 1998) |
| uropygial gland | A compound alveolar gland of birds located on the dorsum of the tail or pygostyle; the secretion of this gland (fatty acids and wax) exits from a papilla on the dorsal surface at the base of the tail feathers; the bird applies the substance to its feathers by means of the bill when preening. The uropygial gland is lacking in some species but its waterproofing ability is essential to water birds. Synonym: glandula uropygius, oil glands, preen gland. (05 Mar 2000) |
| uropygium | <anatomy> The prominence at the posterior extremity of a bird's body, which supports the feathers of the tail; the rump; sometimes called pope's nose. Origin: NL, fr. Gr, (corrupted form); the end of the os sacrum + rump. Source: Websters Dictionary (01 Mar 1998) |
