Carotenoids: more than just beta-carotene.
Fruits and vegetables of the human diet contain many of the over 600 carotenoid pigments that have been identified in plants. Led by work with beta-carotene, researchers have constantly been learning more about the metabolism of these compounds in the human body. Research work is now expanding beyond beta-carotene in an effort to understand what happens to all the pigments found in the human di...
متن کاملCarotene Hydroxylase Activity Determines the Levels of Both α-Carotene and Total Carotenoids in Orange Carrots.
The typically intense carotenoid accumulation in cultivated orange-rooted carrots (Daucus carota) is determined by a high protein abundance of the rate-limiting enzyme for carotenoid biosynthesis, phytoene synthase (PSY), as compared with white-rooted cultivars. However, in contrast to other carotenoid accumulating systems, orange carrots are characterized by unusually high levels of α-carotene...
متن کاملb-Carotene and other carotenoids in protection from sunlight
Protection against skin damage from sunlight by nutritional means has been examined. Likewise, there has been work on the topical application of phytochemicals to the skin. This review focuses on the nutritional aspect of phytochemicals in humans—ie, the provision of carotenoid micronutrients by dietary means to the skin and their role in protection. Human intervention studies have documented p...
متن کاملBeta-carotene, carotenoids, and disease prevention in humans.
A growing body of literature exists regarding the effects of beta-carotene and other carotenoids on chronic diseases in humans. This article reviews and critically evaluates this literature and identifies areas for further research. This review is restricted to studies in humans, with a major emphasis on the most recent literature in the area of carotenoids and selected cancers. Effects of caro...
متن کاملAntioxidant activity of beta-carotene-related carotenoids in solution.
The effect of the antioxidant activity of beta-carotene and related carotenoids on the free radical-oxidation of methyl linoleate in solution was examined by measuring the production of methyl linoleate hydroperoxides. Canthaxanthin and astaxanthin which possess oxo groups at the 4 and 4'-positions in the beta-ionone ring retarded the hydroperoxide formation more efficiently than beta-carotene ...
