Which compound derived from soybeans acts as a phytoestrogen?

1. Estrogen

2. Progesterone

3. Isoflavones

4. Resveratrol

The correct answer is: Isoflavones

Isoflavones, which are compounds derived from soybeans, are known for their phytoestrogenic properties. Phytoestrogens are plant-derived compounds that can mimic or modulate the effects of estrogen in the body due to their structural similarities to the hormone. This ability allows isoflavones to bind to estrogen receptors, which may influence various physiological processes, including hormone regulation, bone health, and menopausal symptoms. In the context of soy products, isoflavones such as genistein and daidzein have been studied for their potential health benefits, including reducing the risk of certain cancers and improving overall cardiovascular health. Their role as phytoestrogens is significant, especially for individuals who may experience estrogen deficiency or those seeking natural alternatives for hormone-related conditions. The other compounds listed do not possess phytoestrogen properties derived from plant sources like isoflavones. Estrogen and progesterone are steroid hormones produced by the body, while resveratrol, found in certain plants, exhibits different health benefits but does not act as a phytoestrogen. Hence, isoflavones stand out specifically for their estrogen-like effects derived from soybeans.
