Plant carotenoids: pigments for photoprotection, visual attraction, and human health.
Plant carotenoids are red, orange, and yellow lipid-soluble pigments found embedded in the membranes of chloroplasts and chromoplasts. Their color is masked by chlorophyll in photosynthetic tissues, but in late stages of plant development these pigments contribute to the bright colors of many flowers and fruits and the carrot root. Carotenoids protect photosynthetic organisms against potentiall...
متن کاملCarotenoids in plant photoprotection
One of the roles of carotenoids in plants which are proposed is to serve as protecting agents against deleterious effects of light. The major mechanisms whereby carotenoids prevent harmful photooxidations in vitro and their suggested protective function in photosynthetic tissue, i.e. chioroplasts, will be summarized briefly. Fungi are non—photosynthetic plants, therefore lack the antenna functi...
متن کاملCarotenoids and human health.
Oxidative stress is an important contributor to the risk of chronic diseases. Dietary guidelines recommend increased consumption of fruits and vegetables to combat the incidence of human diseases such as cancer, cardiovascular disease, osteoporosis and diabetes. Fruits and vegetables are good sources of antioxidant phytochemicals that mitigate the damaging effect of oxidative stress. Carotenoid...
متن کاملPhotoprotection by carotenoid pigments in the copepod Diaptomus nevadensis.
Individuals of the copepod Diaptomus nevadensis that contain high concentrations of carotenoids survive significantly better in natural intensities of visible light than less pigmented copepods. Vertical migration and behavior in light of different wave lengths are related to the degree of pigmentation.
