The biosynthesis of astaxanthin.X. the carotenoids in the red carp, cyprinus carpio linne, and the interconversion of β-[15,15′-3H2]carotene into their body astaxanthin
Date of Original Version
1. 1. In red carp the existence of lutein ester, zeaxanthin ester, α-doradexanthin ester (3,3′-dihydroxy-4′-keto-α-carotene), and astaxanthin ester was confirmed. 2. 2. Dietary β- [15,15′- 3H2] carotene was not converted to astaxanthin ester, so it was shown that in red carp β-carotene was not a precursor of astaxanthin ester. 3. 3. Dietary labelled astaxanthin was transferred to the body astaxanthin ester of red carp by feeding them labelled astaxanthin. 4. 4. In red carp a metabolic pathway from lutein ester to astaxanthin ester through the α-doradexanthin ester step was proposed. © 1972.
