Genistein:4',5,7-Trihydroxyisoflavone.:Introduction and Its Benefit Applications.

Introduction:Genistein.

Genistein:4',5,7-Trihydroxyisoflavone CAS 446-72-0 EINECS ELINCS No 207-174-9 isoflavone,flavonoids,phytoestrogens,antioxidant photo picture image Genistein is an isoflavonoid phytoestrogenic compound found in soybeans, pea pods, and other legumes. The estimated human normal dietary intake of genistein, primarily as glycosides, is 0 to 0.5 mg/kg. Genistein is present in much greater amounts in nutritional supplements. Genistein is carcinogenic in female neonatal mice, inducing endocrine-dependent uterine tumors in a fashion similar to diethylstilbestrol (DES).Genistein is a tyrosine-specific inhibitor of protein kinase activity, blocking the tyrosine-phosphorylation of histone H2B. In adult animals, dietary genistein has chemopreventive effects on breast, prostate, and other endocrine-dependent tumors.

Genistein is an isoflavone belonging to the group of flavonoids. Because of this similarity of the structure of genistein to that of estrogen genistein is also a phytoestrogens, together with daidzein.Genistein is the aglycone (without sugar component) of the glycoside genistin.

The main source of genistein is the glucoside genistin. Before genistein can act it first needs to be released from genistin. This normally happens in the stomach (acid hydrolysis) and intestine (action of bacterial enzymes). Some genistein supplements contain genistein which has been hydrolysed in a chemical process.

Genistein is one of several known isoflavones. Isoflavones, such as genistein and daidzein, are found in a number of plants, with soybeans and soy products like tofu and textured vegetable protein being the primary food source. Soy isoflavones are a group of compounds found in and isolated from the soybean. Besides functioning as antioxidants, many isoflavones have been shown to interact with animal and human estrogen receptors, causing effects in the body similar to those caused by the hormone estrogen. Soy isoflavones also produce non-hormonal effects.
