ESTRADIOL BIOSYNTHETIC PATHWAY (PW:0000781)

Description

Estrogen hormones are responsible for the development and maintenance of female phenotype and reproductive functions and a range of other processes in nonreproductive tissues. Estradiol, the main C18 estrogen, is primarily synthesized in the ovaries. Like all steroid hormones, estrogens are derived from cholesterol; their biosynthesis is tightly regulated by the hypothalamus-pituitary-gonadal axis. The chronic steroidogenic response involves the change in the expression of steroidogen
