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.
Function:
Estrone (E1, and also oestrone) is an estrogenic hormone secreted by the ovary as well as adipose tissue with the chemical name of 3-hydroxyestra-1,3,5(10)-triene-17-one and the chemical formula C18H22O2. Estrone is an odorless, solid crystalline powder, white in color with a melting point of 254.5 °C and a specific gravity of 1.23.Estrone is one of several natural estrogens, which also include estriol and estradiol. Estrone is the least abundant of the threehormones; estradiol is present almost always in the reproductive female body, and estriol is abundant primarily duringpregnancy.
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 dysfunction.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.
Applications
The official chemical name of estrone is 3-hydroxyestra-1,3,5(10)-triene-17-one with the chemical formula C18H22O2.
Estrone is also named aquacrine, bestrone, crinovaryl, folliculin, 1,3,5-estratriene-3-ol-17-one, estro-a, estronol, erystogen, 3-hydroxyestra-1,3,5(10)-trien-17-one, kestrone 5, propagon-s, menagen, theelin, theogen, destrone, aquacrine, crystogen, oestrin, 1,3,5(10)-estratrien-3-ol-17-one, 1,3,5(10)-oestratrien-3-ol-17-one, and oestrone.
Biosynthesis
Estrone is synthesized via aromatase from androstenedione, a derivative of progesterone. The conversion consists of the de-methylation of C-19 and the aromaticity of the 'A' ring. This reaction is similar to the conversion of testosterone to estradiol.
Estrone is a white, solid crystalline powder that is odorless. It has a melting point of 254.5 °C (490 °F) and has a specific gravity of 1.23. At high temperatures estrone is combustible and the products of combusting estrone are carbon monoxide (CO) and carbon dioxide (CO2).
