Properties and stability

Estrone is an estrogen secreted by mature ovarian follicles (mainly theca cells) and the corpus luteum. It has the same effect as estradiol and can promote and regulate female accessory sexual organs. development, prompting the emergence of female secondary sexual characteristics.

Storage method

Store in a sealed and protected place from light

Synthesis method

1. Made from 17β-estradiol under the action of 17β-hydroxysteroid dehydrogenase.

2.

Purpose

1. It is mainly used to treat uterine hypoplasia, menstrual disorders, menopausal disorders, etc. It is rarely used due to its difficult source.
