beta-Carotene is a strongly-coloured red-orange pigment abundant in plants and fruits.
It is an organic compound and chemically classified as a hydrocarbon and specifically as a terpenoid (isoprenoid), reflecting its derivation from isoprene units. Plant carotenoids are the primary dietary source of provitamin A, with beta-carotene as the most well-known provitamin A carotenoid.Others include alpha-carotene and beta-cryptoxanthin.
Carotenoid absorption is restricted to the duodenum of the small intestine and dependent on Class B scavenger receptor (SR-B1) membrane protein, which are also responsible for the absorption of Vitamin E (alpha-tocopherol).
Buchem BV offers a wide range of stable isotope labelled and unlabelled beta-carotene derivatives.
