一般描述
β-Estradiol is secreted by developing ovaries and is predominant during premenopause in women.
应用
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.
生化/生理作用
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.

In this study we present a pressurized liquid extraction/liquid chromatography-tandem mass spectrometry (PLE/LC-MS-MS) method to determine a group of estrogens and conjugated estrogens in sewage sludge. Parameters that affect the extraction step such as extraction solvent, temperature, pressure, static extraction

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
