99% Anti Estrogen Steroids Female Hormone Powder Estrone CAS 53-16-7

Quick Detail:

Description:
Estrone is one of the three naturally occurring estrogens, the others being estradiol and estriol.Estrone is synthesized from androstenedione by the aromatase enzyme system in the ovaries and placenta, and is also synthesized from estradiol by 17-hydroxy steroid dehydrogenase in the liver.Serum concentrations of estrone in premenopausal women fluctuate according to the menstral cycle and becomes the most predominant estrogen in postmenopausal women. The binding affinities of estrone to the estrogen receptors α and β are approximately 60% and 37% relative to estradiol.

Application:
Estrone is known to be a carcinogen for human females as well as cause breast tenderness or pain, nausea, headache, hypertension, and leg cramps.In men, estrone has been known to cause anorexia, nausea, vomiting, and erectile disfunction. Estrone is relevant to health and disease states because of its conversion to estrone sulfate, a long-lived derivative. Estrone sulfate acts as a reservoir that can be converted as needed to the more active estradiol. It is the predominant estrogen in postmenopausal women.
