General description

β-Estradiol is secreted by developing ovaries and is predominant during premenopause in women.

Application

β-Estradiol 3-sulfate sodium salt has been used to measure the estradiol level from culture supernatant in ultra-performance liquid chromatography-tandem mass spectrometry.

Biochem/physiol Actions

β-Estradiol is a steroid hormone involved in a number of organ functions. It is significantly associated with brain functions including neuroprotection, neurogenesis and synaptic plasticity. β-Estradiol maintains bone homeostasis, hence it is preferred for osteoporosis therapy. 17-β-Estradiol is the most active estrogen generated in our body. During postmenopausal, 17-β-estradiol inhibits oxidative modification in low density lipoprotein. This indicates that estrogen replacement therapy might be useful in treating cardiovascular disease.

A radioisotopic assay for cytoplasmic estradiol-17 beta sulfotransferase activity in rat liver was developed. Routine enzyme assays used 120 microM [3H]estradiol-17 beta, 240 microM 3'-phosphoadenosine-5'-phosphosulfate, and enzyme samples containing up to 0.60 mg of cytosol protein. Livers from males and

The most abundant form of estrogen circulating in fetal plasma is sulfo-conjugated estrogen; for example, estradiol-3-sulfate (E(2)SO(4)) is more highly abundant than estradiol (E(2)). The present study investigated the ontogeny of the deconjugating (steroid sulfatase [STS]) and conjugating (estrogen sulfotransferase
