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.

General description

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