Details
β-Carotene is a strongly-coloured red-orange pigment abundant in plants and fruits. It is an organic compound and chemically is classified as a hydrocarbon and specifically as a terpenoid (isoprenoid), reflecting its derivation from isoprene units. β-Carotene is biosynthesized from geranylgeranyl pyrophosphate.[3] It is a member of the carotenes, which are tetraterpenes, synthesized biochemically from eight isoprene units and thus having 40 carbons. Among this general class of carotenes, β-Carotene is distinguished by having beta-rings at both ends of the molecule. Absorption of β-Carotene is enhanced if eaten with fats, as carotenes are fat soluble.
Used in animal premix and compound feed, Improve animal immunity, enhance the survival rate of breeding animals, can promote animal growth, improve the production performance, especially for female animal breeding performance has obvious effect, and it’s also a kind of effective pigment.
