Carotenoids (C0007271) |
|
|---|---|
| Definition (NCI_NCI-GLOSS) | A yellow, red, or orange substance found mostly in plants, including carrots, sweet potatoes, dark green leafy vegetables, and many fruits, grains, and oils. Some carotenoids are changed into vitamin A in the body and some are being studied in the prevention of cancer. A carotenoid is a type of antioxidant and a type of provitamin. |
| Definition (NCI_CRCH) | Class of compounds usually consisting of a hydrocarbon chain of 40 carbons, nine conjugated double bonds, and one or two cyclic structures at the ends of the conjugated chain. |
| Definition (NCI) | A class of hydrocarbons (carotenes) and their oxygenated derivatives which exhibit chemopreventive properties. Carotenoids are pigments found in green, yellow, and leafy vegetables, and yellow fruits. The pigments are fat-soluble, unsaturated aliphatic hydrocarbons functioning as provitamins and are converted to vitamin A through enzymatic processes in the intestinal wall. |
| Definition (MSH) | The general name for a group of fat-soluble pigments found in green, yellow, and leafy vegetables, and yellow fruits. They are aliphatic hydrocarbons consisting of a polyisoprene backbone. |
| Definition (CSP) | group of fat-soluble pigments found in green, yellow, and leafy vegetables, and yellow fruits; they are aliphatic hydrocarbons consisting of a polyisoprene backbone. |

Beta Carotene (C0053396) |
|
|---|---|
| Definition (NCI_CRCH) | Carotenoid consisting of a cyclic structure on each end with additional double bonds at the number 5 and 5' carbon atoms of the cyclic structures. |
| Definition (NCI) | A naturally-occurring retinol (vitamin A) precursor obtained from certain fruits and vegetables with potential antineoplastic and chemopreventive activities. As an anti-oxidant, beta carotene inhibits free-radical damage to DNA. This agent also induces cell differentiation and apoptosis of some tumor cell types, particularly in early stages of tumorigenesis, and enhances immune system activity by stimulating the release of natural killer cells, lymphocytes, and monocytes. (NCI04) |
| Definition (NCI_NCI-GLOSS) | A substance found in yellow and orange fruits and vegetables and in dark green, leafy vegetables. The body can make vitamin A from beta carotene. Beta carotene is being studied in the prevention of some types of cancer. It is a type of antioxidant. |
| Definition (MSH) | A carotenoid that is a precursor of VITAMIN A. It is administered to reduce the severity of photosensitivity reactions in patients with erythropoietic protoporphyria (PORPHYRIA, ERYTHROPOIETIC). (From Reynolds JEF(Ed): Martindale: The Extra Pharmacopoeia (electronic version). Micromedex, Inc, Engewood, CO, 1995.) |
| Definition (PDQ) | A naturally-occurring retinol (vitamin A) precursor obtained from certain fruits and vegetables with potential antineoplastic and chemopreventive activities. As an anti-oxidant, beta carotene inhibits free-radical damage to DNA. This agent also induces cell differentiation and apoptosis of some tumor cell types, particularly in early stages of tumorigenesis, and enhances immune system activity by stimulating the release of natural killer cells, lymphocytes, and monocytes.
