Many kinds of carotenoids are found in algae and, recently, taxonomic studies of algae have been developed. In this review, the relationship between the distribution of carotenoids and the phylogeny of oxygenic phototrophs in sea and fresh water, including cyanobacteria, red algae,...

More than 600 carotenoids are found in nature, but only a fraction play a known role in health and disease. Carotenoids are not made by the body and must be supplied from food or supplements. Their concentration in blood is associated with a variety of positive health outcomes, yet more ...
Carotenoids are found in high concentrations in yellow and orange leaves or vegetables. This color is seen because the carotenoid pigments: a. absorb all wavelengths of light and then transmit yellow and orange wavelengths. b. absorb or reflect yellow and ...
The carotenoids occur in solution in fat depots, in colloidal dispersion in lipoid media, or combined with protein in the aqueous phase. Carotenoids are found in flowers, leaves, roots, fruit, algae, bacteria, fish, mammalian ovaries, and muscle. Carotenoids may be extracted by maceration of ...
Carotenoids are a class of phytonutrients ("plant chemicals") and are found in the cells of a wide variety of plants, algae and bacteria. They help plants absorb light energy for use inphotosynthesis. They also have an important antioxidant function of deactivating free radicals — single oxygen...
Of more than 600 carotenoids identiÆed to date, about 40 carotenoids are found in ourdaily foods. Thus, we decided to evaluate the biological activities of these carotenoids, and found thatsome showed more potent activity thanb-carotene in suppressing the process of carcinogenesis. It is of...
Carotenoids belong to the category of phytonutrients and are found within the cells of a broad spectrum of organisms, encompassing bacteria, algae, and plants. Although foods rich in carotenoids are generally recognized by their red, yellow, or orange coloration, exceptions do exist. It is worth ...
Carrots are the best-known dietary source of carotenoids, although they are also found in many other orange fruits and vegetables such as pumpkins, sweet potatoes, cantaloupes, mangoes, and papayas.
