Application

  • β-Carotene has been used as a standard to measure β-carotene levels in plasma samples via HPLC (high performance liquid chromatography).
  • It has been used to study the effects of vitamins on growth of Mycobacteria in radiometric culture.
  • It has been used as a supplement in the growth medium of Drosophila melanogaster to allow intake of vitamin A.

Biochem/physiol Actions

The most important of the provitamins A, β-carotene can be classified as an antioxidant due to its inhibition of radical initiated peroxidation in vitro. However, in vivo it appears to act either as an antioxidant or a prooxidant depending on cellular environment. It reduces the incidence of many cancers, but enhances lung cancer incidence in smokers.
The most important of the provitamins A.

Mixtures of neutral lipids containing cholesteryl esters and beta-carotene were used to reconstitute the lipid core of heptane-extracted low-density lipoproteins (LDL). The resulting preparations of reconstituted LDL, referred to as r-[cholesteryl ester + beta-carotene]LDL, exhibited temperature-dependent circular dichroism (CD) in
