echinenone

Echinenone/ (Myxoxanthin)

C40H54O (550.4174)

A carotenone that is beta-carotene in which the 4 position has undergone formal oxidation to afford the corresponding ketone. Isolated as orange-red crystals, it is widely distributed in marine invertebrates.

(3R,6R)-3-Hydroxy-3,4-didehydro-β,γ-carotene is a carotenoid found in human serum and breast milk (PMID: 9164160). Carotenoids are isoprenoid molecules that are widespread in nature and are typically seen as pigments in fruits, flowers, birds and crustacea. Animals are unable to synthesise carotenoids de novo, and rely upon the diet as a source of these compounds. Over recent years there has been considerable interest in dietary carotenoids with respect to their potential in alleviating age-related diseases in humans. This attention has been mirrored by significant advances in cloning most of the carotenoid genes and in the genetic manipulation of crop plants with the intention of increasing levels in the diet. Studies have shown an inverse relationship between the consumption of certain fruits and vegetables and the risk of epithelial cancer. Since carotenoids are among the micronutrients found in cancer preventive foods, detailed qualitative and quantitative determination of these compounds, particularly in fruits and vegetables and in human plasma, have recently become increasingly important.
