일반 설명
Daidzein is an endocrine-active estrogenic isoflavone. This phytoestrogen is capable to bind to estrogen to exert estrogenic effects in vivo. It can naturally be found in soybean seed and flour.
애플리케이션
Daidzein was used as standard in determination of daidzein and genistein, in soybean food using in-tube solid-phase microextraction coupled to high-performance liquid chromatography (in-tube SPME–HPLC). It was also used as reference standard in determination of isoflavones in red clover using high-performance liquid chromatography–UV–electrospray ionization-mass spectrometric detector (HPLC–UV–ESI-MSD).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
생화학적/생리학적 작용
Soy isoflavone daidzein protects against oxidative damage in liver cells induced by 7,12-dimethylbenz[a]anthracene (DMBA). Catalase and superoxide dismutase activity, down-regulated by DMBA, was restored by daidzein.

Isoflavones are an important class of phytoestrogens that are found at extrememly high levels in soy. Up until recently, daidzein and genistein were considered to be the most important and hence most studied isoflavones, however more recently attention has shifted

Isoflavones (genistein, daidzein, and glycitein) are suggested to have benefits as well as risks for human health. Approximately one-third of the Western population is able to metabolize daidzein into the more potent metabolite equol. Having little endogenous estradiol, equol-producing postmenopausal
