Catechol estrogen

A catechol estrogen is a steroidal estrogen that contains catechol (1,2-dihydroxybenzene) within its structure. The catechol estrogens are endogenous metabolites of estradiol and estrone and include the following compounds: * 2-Hydroxylated: * 2-Hydroxyestradiol * 2-Hydroxyestrone * 2-Hydroxyestriol * 4-Hydroxylated: * 4-Hydroxyestradiol * 4-Hydroxyestrone * 4-Hydroxyestriol
