| zeta | 1. 6th Letter of the Greek alphabet, &zeta, 2. In chemistry, denotes the sixth in a series, e.g., the sixth carbon from a functional group. 3. Symbol for electrokinetic potential. (05 Mar 2000) |
| zeta crystallin-NADPH oxidoreductase | <chemical> Do not confuse with protein p36 (= annexin II); base sequence given in first source Synonym: p36 gene product, leishmania (26 Jun 1999) |
| zeta potential | <chemistry> The electrostatic potential of a molecule or particle, for example cell measured at the plane of hydrodynamic slippage outside the surface of the molecule or cell. Usually measured by electrophoretic mobility. Related to the surface potential and a measure of the electrostatic forces of repulsion the particle or molecule is likely to meet when encountering another of the same sign of charge. See: cell electrophoresis. (18 Nov 1997) |
| zeta sedimentation ratio | The ratio of the zetacrit to the haematocrit, normally 0.41 to 0.54 (41 to 54%); it is a sensitive indicator of the erythrocyte sedimentation rate (ESR) and, unlike the latter, is unaffected by anaemia, which tends to elevate the ESR. (05 Mar 2000) |
| beta-carotene | An antioxidant which protects cells against oxidation damage that can lead to cancer. Beta carotene is converted, as needed, to vitamin A. A yellow carotenoid pigment that gives a reddish colour to plants such as carrots and tomatoes. It is often used as a vitamin supplement because the liver can convert it into Vitamin A. Food sources of beta-carotene include vegetables such as carrots, sweet potatoes, spinach and other leafy green vegetables; and fruit such as cantaloupes and apricots. Excessive carotene in the diet can temporarily yellow the skin, a condition called carotenaemia, commonly seen in infants fed largely mushed carrots. (12 Dec 1998) |
| beta-carotene 15,15'-dioxygenase | <enzyme> An enzyme catalyzing the reaction of beta-carotene plus O2 producing two retinals. Synonym: beta-carotene cleavage enzyme, carotenase, carotinase. (05 Mar 2000) |
| beta-carotene cleavage enzyme | <enzyme> An enzyme catalyzing the reaction of beta-carotene plus O2 producing two retinals. Synonym: beta-carotene cleavage enzyme, carotenase, carotinase. (05 Mar 2000) |
| beta-carotene hydroxylase | <enzyme> O2-dependent NADPH-dependent monooxygenase from erwinia herbicola; forms zeaxanthin; amino acid sequence has been determined; genbank m87280 Registry number: EC 1.14.13.- Synonym: beta-carotene monooxygenase, crtz gene product (26 Jun 1999) |
| carotene | <biochemistry> Hydrocarbon carotenoids usually with 9 conjugated double bonds. _ carotene is the precursor of Vitamin A, each molecule giving rise to two Vitamin A molecules. (18 Nov 1997) |
| carotene, beta | An antioxidant which protects cells against oxidation damage that can lead to cancer. Beta-carotene is converted, as needed, to vitamin A. Food sources of beta carotene include vegetables such as carrots, sweet potatoes, spinach and other leafy green vegetables; and fruit such as cantaloupes and apricots. Excessive carotene in the diet can temporarily yellow the skin, a condition called carotenaemia, commonly seen in infants fed largely mushed carrots. (12 Dec 1998) |
| carotene oxidase | <enzyme> Enzyme that catalyses the oxidative conversion of arachidonic acid to the hydroxyeicosenoic acid (HETE) structure in the synthesis of leucotrienes. (18 Nov 1997) |
