| uric acid | <biochemistry> The final product of nitrogenous excretion in animals that require to conserve water, such as terrestrial insects or have limited storage space, such as birds and their eggs. Uric acid has very low water solubility and crystals may be deposited in, for example: butterflies wings to impart irridescence. Uric acid, a crystalline body, present in small quantity in the urine of man and most mammals. Combined in the form of urate of ammonia, it is the chief constituent of the urine of birds and reptiles, forming the white part. Traces of it are also found in the various organs of the body. It is likewise a common constituent, either as the free acid or as a urate, of urinary or renal calculi and of the so-called gouty concretions. From acid urines, uric acid is frequently deposited, on standing in a cool place, in the form of a reddish yellow sediment, nearly always crystalline. Chemically, it is composed of carbon, hydrogen, nitrogen, and oxygen, and by decomposition yields urea, among other products. It can be made synthetically by heating together urea and glycocoll. It was formerly called also lithic acid, in allusion to its occurrence in stone, or calculus. See: tophus. Structure: C5H4N4O3 Source: Websters Dictionary (18 Nov 1997) |

| uric acid infarct | <nephrology, paediatrics> Precipitates of uric acid distending renal collecting tubules in the newborn; since there is no necrosis, the term infarct is a misnomer. (20 Jun 2000) |
| uric acid oxidase | <enzyme> An enzyme that catalyses the conversion of urate and unidentified products. It is a copper protein. The initial products decompose to form allantoin. Chemical name: Urate:oxygen oxidoreductase Registry number: EC 1.7.3.3 (12 Dec 1998) |

| reagent | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. The adjacent hydroxyl groups are oxidized to form aldehydes by periodic acid (HIO4) and these aldehyde groups react with Schiff's reagent (basic fuchsin decolourised by sulphurous acid) to give a purple colour.
