Synthesis of carotenoid-cysteine conjugates.
Isozeaxanthin under acidic conditions forms an allylic cation which reacts readily with thiol nucleophiles. With N-acetylcysteine as a nucleophile the products obtained are carotenoid-cysteine conjugates in which the amino acid moiety is attached to the carotenoid via sulphur in position 4. The water solubility of the products can be increased by deprotection of the amino group. The antioxidant...
متن کاملSome studies on carotenoid synthesis.
INTRODUCTION Traditionally synthesis is invoked as the final proof of a structure deduced by other means. In the carotenoid field synthesis is being used increasingly as an integral part of structural studies in order to elucidate some molecular feature for which the other evidence is inconclusive or ambiguous. Synthesis also fulfils the very important role of making many carotenoids much more ...
متن کاملEffects of Hibiscus rosasiensis as a natural carotenoid on growth performance, body composition, pigmentation and carotenoid in blood plasma of blue gourami, Trichogaster trichopterus at different stocking densities
This study examined the effects of the supplementation of China rose powder of Hibiscus rosasiensis towards blue gourami with different stocking densities.China rose (1.5%) was used on two different stocking densities (20 and 30 fishes per aquarium). The group that contain a total of 20 (individual/aquarium) and 30 (individual/aquarium) densities of fishes, are referred as CH1 and CH2 respectiv...
متن کاملEffects of Hibiscus rosasiensis as a natural carotenoid on growth performance, body composition, pigmentation and carotenoid in blood plasma of blue gourami, Trichogaster trichopterus at different stocking densities
This study examined the effects of China rose powder (Hibiscus rosasiensis) supplementation (1.5%) on the growth performance, body composition, and pigmentation of blue gourami at different stocking densities (0.6 and 0.9 fish L-1). Four treatments were assigned in this study: China rose diet+0.6 fish L-1 (CG0.6), China rose diet+0.9 fish L-1 (CG0.9), control diet+0.6 fish L-1 (C0.6) and contro...
متن کاملCarotenoid-binding proteins; accessories to carotenoid function.
Understanding of the widespread biological importance of carotenoids is increasing. Accompanying this is the developing recognition that the interaction of carotenoids with other molecules, such as proteins, is also essential. Here the significance of carotenoid-protein interactions with respect to biological function is reviewed for three well characterised carotenoprotein complexes; crustacya...
