Carotenoids in sea urchins
Date of Original Version
β-Echinenone, isolated as a major carotenoid in the gonads of the edible sea urchins, is oxidatively formed from β-carotene via β-isocryptoxanthin. It affects gonad color, reproduction, development, and phagocytosis in the sea urchin. Xanthophylls such as fucoxanthin, lutein, and zeaxanthin do not affect gonad color but have significant effects on fecundity and survival of larvae. Most of the β-echinenone fraction in the gonads (ovaries and testes) consists of the 9′-cis-isomer. The cis-carotenoid may have a specific function in the sea urchin, possibly related to reproduction.
