Isoflavone, in the process of plant phenylalanine metabolism, are extended by cinnamoyl-CoA side chain to form a phenolic compound based on the benzophenone ring, and the 3-phenyl derivative is isoflavone. Plant secondary metabolites. Flavonoids, an aromatic oxygen-containing heterocyclic compound, an isomer of flavonoids. The refined isoflavones are in the form of flakes or needle crystals. Generally colorless, but with the increase of hydroxyl groups, it can be yellow to dark yellow. It is a pigment widely distributed in higher plants. Some isoflavones are phytoalexins and some are used for the treatment of cardiovascular diseases.
There are many different effects of isoflavones. Here is a list of the following:
Prevention of menopausal syndrome
Before and after menopause, due to ovarian dysfunction, the level of estrogen in the body decreases, causing the function adjustment of various organs and tissues to be incompatible, and a series of diseases appear, and the supplement of estrogen can achieve the purpose of preventing and treating such diseases.
Prevent and improve osteoporosis
Osteoporosis refers to a decrease in bone tissue that causes bones to be brittle and fragile, and is prone to fracture. Common in menopausal women and older men (due to hormonal changes or insufficient calcium and vitamin D). The incidence of osteoporosis in middle-aged and older women is much higher than that in men. The main reason is that estrogen levels decline after ovarian function decline, bone metabolism is negatively balanced, and bone mass is reduced. Isoflavones bind to estrogen receptors on bone cells, reduce bone loss, increase body's absorption of calcium, and increase bone density.
Prevention of breast cancer
Long-term use of estrogen alone can increase the incidence of breast cancer and endometrial cancer by 5 to 7 times. Soy isoflavones are similar in structure to estrogens, so they bind to female receptors on the cell surface and activate other anti-cancer mechanisms, reducing the risk of endometrial cancer and breast cancer in women with high levels of estrogen.
Soy products contain five known anti-cancer factors, one of which is phytoestrogens (isoflavones), which are unique anti-cancer factors for soy foods. Scientists have concluded that the anti-oxidant properties of genistein and the prevention of proliferation are the main reasons for its anti-cancer effect. Soy isoflavones have obvious therapeutic effects on breast cancer, colon cancer, lung cancer, prostate cancer, skin cancer and leukemia. Soy isoflavones can also prevent the occurrence of ovarian cancer, colon cancer, stomach cancer and prostate cancer. and many more.
