Estriol CAS: 50-27-1

Estriol  CAS: 50-27-1

Estriol (E3), or oestriol, also known as 16α-hydroxyestradiol or as estra-1,3,5(10)-triene-3,16α,17β-triol, is a natural steroidal estrogen and one of the three main estrogens in the human body.Production of estriol by the ovaries is almost undetectable in non-pregnant women. However, during pregnancy, estriol is synthesized in very high amounts by the placenta and is by far the most produced estrogen in the body,although circulating levels are similar to those of other estrogens due to a relatively high rate of metabolism and excretion.

Description About Estriol CAS: 50-27-1 :

Estriol (E3), or oestriol, also known as 16α-hydroxyestradiol or as estra-1,3,5(10)-triene-3,16α,17β-triol, is a natural steroidal estrogen and one of the three main estrogens in the human body.Production of estriol by the ovaries is almost undetectable in non-pregnant women. However, during pregnancy, estriol is synthesized in very high amounts by the placenta and is by far the most produced estrogen in the body,although circulating levels are similar to those of other estrogens due to a relatively high rate of metabolism and excretion.

Estriol is produced in notable quantities only during pregnancy.Levels of estriol increase 1,000-fold during pregnancy,whereas levels of estradiol and estrone increase 100-fold, and estriol accounts for 90% of the estrogens in the urine of pregnant women.At term, the daily production of estriol by the placenta is 35 to 45 mg,[8] and levels in the maternal circulation are 8 to 13 ng/dL.
