| 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 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) |
| 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) |
| 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) |
