Application: Estriol has been used as a sex hormone to determine its binding constants to insulin (INS), the insulin receptor (IR), and INS-like peptides derived from the IR.
Biochem/physiol Actions: Estriol is a metabolite of 17β-estradiol with much lower biological activity. It is the primary estrogen found in the urine. Large quantities of estriol and estrone are produced by the placenta during pregnancy. These are also the primary estrogens produced by adipose tissue in men and post-menopausal women. Estriol may exhibit immunomodulatory benefits against various diseases such as autoimmune, inflammatory, and neurodegenerative conditions.
