Because it has a low oral bioavailability on its own, estradiol is commonly formulated with an ester side-chain. [DB00977] (EE) is a synthetic form of estradiol commonly used as the estrogenic component of most combination oral contraceptive pills (OCPs).

Estradiol (E2), also called oestrogen, oestradiol, is an estrogen steroid hormone and the major female sex hormone. It is involved in the regulation of female reproductive cycles such as estrous and menstrual cycles.

Estradiol, the prototypical estrogen. Steroid ring system. This is a list of steroidal estrogens or derivatives of estradiol, estrone, and estriol. Most esters of these estrogens are not included in this list; for esters, see here instead. Estradiol 21,16α-lactone? ? …

Estrogens (also oestrogens) are a group of steroid compounds, named for their importance in the oestrus cycle, functioning as the primary female sex hormone. While estrogens are present in both men and women, they are usually present at significantly higher levels in women of reproductive age.

Estrogen is produced in the ovaries and secreted into the blood, whereupon it enters target cells throughout the body. It enters the cells via passive diffusion and binds to specific proteins called estrogen receptors ,

Estradiol contains total 44 atom(s); 24 Hydrogen atom(s), 18 Carbon atom(s), and 2 Oxygen atom(s). Learn more about estradiol chemical formula at Mol-Instincts.
