Common Name

Epipregnanolone

Description

Epipregnanolone, also known as 3beta-hydroxy-5beta-pregnan-20-one, belongs to the class of organic compounds known as gluco/mineralocorticoids, progestogens, and derivatives. These are steroids with a structure based on a hydroxylated prostane moiety. Thus, epipregnanolone is considered to be a steroid lipid molecule. Epipregnanolone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Epipregnanolone is a pregnane found in the urine of pregnant women and sows. It has anesthetic, hypnotic, and sedative properties. It is a substrate of the enzyme 3beta-hydroxy-5beta-steroid dehydrogenase (EC 1.1.1.277).
