Carotene Chemical Properties,Usage,Production
Description
α-Carotene is a precursor of vitamin A that has been found in various fruits and vegetables. It inhibits proliferation of GOTO human neuroblastoma cells more potently than β-carotene and halts the cell cycle at the G0/G1 phase concomitantly with a reduction in the mRNA expression of the protooncogene N-Myc. It is also more potent than β-carotene in mouse models of skin and lung carcinogenesis and decreases the number of hepatomas in mice with spontaneous liver carcinogenesis when administered in drinking water at a concentration of 0.05%. α-Carotene levels are increased in patients with coronary heart disease and are inversely correlated with the risk of estrogen receptor-negative breast cancer.
Uses
carotene is used to provide a red-orange color in cosmetic formulations. It is the primary yellow coloring component of butter, carrots, and egg yolk. Carotene is found in plants as well as in many animal tissues.
Uses
Carotene is a colorant and provitamin, being a hydrocarbon which is one of two subgroups of the carotenoids (yellow, orange, or red pig- ments). the other subgroup is xanthophylls. functions as a colorant with beta-apo-8-carotenal being a red-orange carotenoid and betabeing a yellow carotenoid. it is also a vitamin a precursor that is converted by the body to vitamin a. it is used in ice cream, cheese, and other dairy products.
Uses
(6''R)-β,ε-Carotene is a trans isomer of carotenoid pigment found in plants. It is a terpenoid hydrocarbon.
Definition
ChEBI: (6'R)-beta,epsilon-carotene is an alpha-carotene. It is an enantiomer of a (6'S)-beta,epsilon-carotene.
General Description
α-Carotene is a carotenoid, which shows anticarcinogenic activity.
Biochem/physiol Actions
One of the primary isomers of carotene, enantiomerically pure form of metabolite in carotenoid biosynthesis, biosynthesis of plant secondary metabolites, biosynthesis of terpenoids and steroids and the biosynthesis of secondary metabolites.
Purification Methods
Purify α-carotene by chromatography on columns of calcium hydroxide, alumina or magnesia. Crystallise it from CS2/MeOH, toluene/MeOH, diethyl ether/pet ether, or acetone/pet ether. Store it in the dark, under N2 or Ar at -20o. It gives a blue colour with max at 542nm when mixed with SbCl3 in CHCl3. [Karrer & Walker Helv Chim Acta 16 641 1933, Eugster et al.
