Natural Beta-Carotene is an natural-source compound - a terpenoid, a red-orange pigment abundant in plants and fruits. As a carotene with β-rings at both ends, it is the most common form of carotene. It is a precursor (inactive form) of vitamin A. Being highly conjugated, it is deeply colored, and as a hydrocarbon lacking functional groups, it is very lipophilic.
When ingested into the body, beta-carotene is converted to vitamin A (retinol) in the small intestines of the mammals by beta-carotene 15 and 15 monooxygenase, an enzyme. Excess retinol is stored in the liver and synthesized into active vitamin A in times of need.
