Application

16α-Hydroxydehydroepiandrosterone (16OH-DHEA) is a metabolite of the endogenous steroid hormone dehydroepiandrosterone (DHEA). It is formed upon 16-hydroxylation by the cytochrome P450 (CYP) enzyme CYP3A4 and fetal/neonatal form CYP3A7. 16OH-DHEA is the precursor of fetal 16alpha-hydroxylated estrogens, the main phenolic steroids in pregnancy. Their serum levels are used as biochemical markers of the well being of the fetus. In adults, increased levels of 16-hydroxylated estrogens are thought to correlate with the risk of cancer and some systemic autoimmune diseases.
