2-Hydroxyestradiol is a catechol estrogen and in this regard bears some structural resemblance to the catecholamines dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline). [6] In accordance, 2-hydroxyestradiol has been found to interact with catecholamine systems. [ 6 ]

Estrogen levels change throughout the menstrual cycle, too, peaking during ovulation. But, “generally, levels of estradiol (E2) between 30 to 400 pg/mL are considered normal during reproductive ...
The hydroxylation of estradiol is one of the major routes of metabolism of the estrogen steroid hormone estradiol. It is hydroxylated into the catechol estrogens 2-hydroxyestradiol and 4-hydroxyestradiol and into estriol (16α-hydroxyestradiol), reactions which are catalyzed by cytochrome P450 enzymes predominantly in the liver , but also in ...
That’s because a diet high in sweets, dairy, refined grains, red meat, and processed foods can raise estrogen levels and promote insulin resistance due to higher body fat, she explains.
Tryptophan hydroxylase (TPH) is an enzyme (EC 1.14.16.4) involved in the synthesis of the monoamine neurotransmitter serotonin. Tyrosine hydroxylase , phenylalanine hydroxylase , and tryptophan hydroxylase together constitute the family of biopterin-dependent aromatic amino acid hydroxylases .
2-Hydroxyestrone (2-OHE1), also known as estra-1,3,5(10)-trien-2,3-diol-17-one, is an endogenous, naturally occurring catechol estrogen and a major metabolite of estrone and estradiol. [ 1 ] [ 2 ] [ 3 ] It is formed irreversibly from estrone in the liver and to a lesser extent in other tissues via 2- hydroxylation mediated by cytochrome P450 ...
During menopause, estrone is the predominant circulating estrogen and during pregnancy estriol is the predominant circulating estrogen in terms of serum levels. Given by subcutaneous injection in mice, estradiol is about 10-fold more potent than estrone and about 100-fold more potent than estriol. [ 14 ]
