[1] [3] 2-OHE1 is the most abundant catechol estrogen in the body. [ 3 ] 2-Hydroxyestrone is not significantly uterotrophic in bioassays , whereas other hydroxylated estrogen metabolites including 2-hydroxyestradiol , 16α-hydroxyestrone , estriol (16α-hydroxyestradiol), 4-hydroxyestradiol , and 4-hydroxyestrone all are.
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 .

If you suspect your estrogen levels are high or simply want to get tested, a gynecologist, endocrinologist, or primary care physician can order a blood test to measure your levels, says Dr. Woo.
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 ...
Hypertryptophanemia is a rare autosomal recessive [2] metabolic disorder that results in a massive buildup of the amino acid tryptophan in the blood, with associated symptoms and tryptophanuria (-uria denotes 'in the urine'). [3] [4] Elevated levels of tryptophan are also seen in Hartnup disease, [5] a disorder of amino acid transport. [6]
The Estradiol blood test measures the amount of estradiol in the blood. [77] It is used to check the function of the ovaries, placenta, adrenal glands. [ 77 ] This can detect baseline estrogen in women with amenorrhea or menstrual dysfunction, and to detect the state of hypoestrogenicity and menopause.
Aromatase deficiency is a rare condition characterized by extremely low levels or complete absence of the enzyme aromatase activity in the body. [2] It is an autosomal recessive disease resulting from various mutations of gene CYP19 (P450arom) which can lead to ambiguous genitalia and delayed puberty in females, continued linear growth into adulthood and osteoporosis in males and virilization ...
