orange pigments . α-Carotene – to vitamin A carrots, pumpkins, maize, tangerine, orange.; β-Carotene – to vitamin A dark, leafy greens, red, orange and yellow fruits and vegetables.
Phytochemicals are chemical compounds produced by plants, generally to help them resist fungi, bacteria and plant virus infections, and also consumption by insects and other animals. The name comes from Greek φυτόν (phyton) 'plant'.
Carotenoids give the characteristic color to pumpkins, carrots, parsnips, corn, tomatoes, canaries, flamingos, salmon, lobster, shrimp, and daffodils. Over 1,100 identified carotenoids can be further categorized into two classes – xanthophylls (which contain oxygen) and carotenes (which are purely hydrocarbons and contain no oxygen).
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants.Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds.
Aside from tomatoes, it is found in red carrots, watermelons, grapefruits, and papayas.It is not present in strawberries or cherries. [4] It has no vitamin A activity. [5]In plants, algae, and other photosynthetic organisms, lycopene is an intermediate in the biosynthesis of many carotenoids, including beta-carotene, which is responsible for yellow, orange, or red pigmentation, photosynthesis ...
Dr. Duke's Phytochemical and Ethnobotanical Databases is an online database developed by James A. Duke at the USDA. The databases report species, phytochemicals, and biological activity, as well as ethnobotanical uses. [1] The current Phytochemical and Ethnobotanical databases facilitate plant, chemical, bioactivity, and ethnobotany searches.
Genistein may act as direct antioxidant, similar to many other isoflavones, and thus may alleviate damaging effects of free radicals in tissues. [24] [25] The same molecule of genistein, similar to many other isoflavones, by generation of free radicals poison topoisomerase II, an enzyme important for maintaining DNA stability. [26] [27] [28]
Phytic acid is a six-fold dihydrogenphosphate ester of inositol (specifically, of the myo isomer), also called inositol hexaphosphate, inositol hexakisphosphate (IP6) or inositol polyphosphate.
