5α-Estran-2-one, also known as 5α-estrone, is a naturally occurring steroid hormone derived from the estrane skeleton. It is a key metabolite of the primary female sex hormone, estradiol, and plays a significant role in the regulation of the menstrual cycle, pregnancy, and other physiological processes. Structurally, 5α-estrone features a ketone group at the C2 position and a 5α-configuration, which distinguishes it from its 5β-isomer. 5α-Estran-2-one is an important biomarker in endocrinology and has been studied for its potential therapeutic applications in various conditions related to hormonal imbalances.
