Description:
Beta-Carotene is an organic, strongly colored red-orange pigment abundant in plants and fruits. It is a member of the carotenes, which are terpenoids (isoprenoids), synthesized biochemically from eight isoprene units and thus having 40 carbons. Among the carotenes, beta-carotene is distinguished by having beta-rings at both ends of the molecule. Beta-Carotene is biosynthesized from geranylgeranyl pyrophosphate.
Beta-Carotene is the most common form of carotene in plants. When used as a food coloring, it has the E number E160a. 119 The structure was deduced by Karrer et al. in 1930. In nature, Beta-carotene is a precursor (inactive form) to vitamin A via the action of beta-carotene 15,15& acute;-monooxygenase.
Usage:
Most important of the provitamins A. Widely distributed in the plant and animal kingdom. In plants it occurs almost always together with chlorophyll. Vitamin A precursor. Ultraviolet screen.
