Natural Product Identification
Common Name16alpha-Hydroxyandrost-4-ene-3,17-dione
Description16A-Hydroxyandrost-4-ene-3,17-dione, also known as 4-androsten-16alpha-ol-3,17-dione or 16alpha-ohad, belongs to the class of organic compounds known as androgens and derivatives. These are 3-hydroxylated C19 steroid hormones. They are known to favor the development of masculine characteristics. They also show profound effects on scalp and body hair in humans. Thus, 16a-hydroxyandrost-4-ene-3,17-dione is considered to be a steroid lipid molecule. 16A-Hydroxyandrost-4-ene-3,17-dione is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 16alpha-Hydroxyandrost-4-ene-3,17-dione is found in Mus musculus. 16A-Hydroxyandrost-4-ene-3,17-dione exists in all living organisms, ranging from bacteria to humans.
