Metabolite Identification
Common Name16-Oxoestrone
DescriptionEstrone (also oestrone) is an estrogenic hormone secreted by the ovary. Its molecular formula is C18H22O2. estrone has a melting point of 254.5 degrees Celsius. estrone is one of the three estrogens, which also include estriol and estradiol. estrone is the least prevalent of the three hormones, estradiol being prevalent almost always in a female body, estriol being prevalent primarily during pregnancy. estrone sulfate is relevant to health and disease due to its conversion to estrone sulfate, a long-lived derivative of estrone. estrone sulfate acts as a pool of estrone which can be converted as needed to the more active estradiol.
