Factory Supply CAS Beta Estradiol Powder/17beta-Estradiol /Estradiol PowderFunction & Usage:

Estradiol (E2 or 17β -estradiol) (also oestradiol) is a sex hormone.Estradiol is the predominant sex hormone present in females. It is also present in males,And at a higher level because it is being constantly produced.In females it is only produced 3 out of 30 days of the cycle. It represents the major estrogen in humans.Estradiol has not only a critical impact on reproductive and sexual functioning, but also affects other organs including the bones.Estrogens direct the development of the female genotype in embryogenesis and at puberty. Estradiol is the major estrogen secreted by the premenopausal ovary. Estradiol benzoate is an estradiol analog which contains a benzyl ester at the C-3 position and is often used in combination with a progestin to induce estrus in domestic livestock. This compound binds to the human and murine estrogen receptor α (ERα), and chicken ER with IC50 values in the range of 22-28 nM. This reflects a 6-10 fold reduction in binding affinity compared to estradiol.
