Sign in to saveAlso known as 7,4'-dihydroxyisoflavone, 4',7-dihydroxy-Isoflavone, 7-hydroxy-3-(4-hydroxyphenyl)-4-benzopyrone, 7-hydroxy-3-(4-hydroxyphenyl)-4H-1-benzopyran-4-one, 4',7-dihydroxyisoflavone, daidzeol, isoaurostatin
Daidzein (7-hydroxy-3-(4-hydroxyphenyl)-4H-chromen-4-one) is a naturally occurring compound found exclusively in soybeans and other legumes, and structurally belongs to a class of compounds known as isoflavones. Daidzein and other isoflavones are produced in plants through the phenylpropanoid pathway of secondary metabolism and are used as signal carriers, and defense responses to pathogenic attacks. Upon consumption of isoflavone-rich foods, daidzein has poor bioavailability and low water solubility.

Daidzein (7-hydroxy-3-(4-hydroxyphenyl)-4H-chromen-4-one) is a naturally occurring compound found exclusively in soybeans and other legumes, and structurally belongs to a class of compounds known as isoflavones. Daidzein and other isoflavones are produced in plants through the phenylpropanoid pathway of secondary metabolism and are used as signal carriers, and defense responses to pathogenic attacks. Upon consumption of isoflavone-rich foods, daidzein has poor bioavailability and low water solubility.
==Natural occurrence== Daidzein and other isoflavone compounds, such as genistein, are present in a number of plants and herbs like kwao krua (Pueraria mirifica) and kudzu. It can also be found in Maackia amurensis cell cultures. Daidzein can be found in food such as mature soybeans and soy products like soy protein concentrate, tofu and textured vegetable protein.
