| Estrone | 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. Group: Pharmaceutical. CAS No. 53-16-7. Pack Sizes: 50 g. Product ID: NP6101. Molecular formula: Custom synthesis is available. Send your inquiries for more information. |  London |

| Estriol | Estriol is a metabolite of 17β-estradiol with much lower biological activity. It is the primary estrogen found in the urine.

Group: Pharmaceutical. CAS No. 50-27-1. Pack Sizes: 20 g. Product ID: B0084-093184. Molecular formula: Custom synthesis is available. Send your inquiries for more information. | London |
