Ambrein

Chemical compound

Ambrein is a triterpene alcohol that is the chief constituent of ambergris, a secretion from the digestive system of the sperm whale. It has been suggested as the possible active component producing the supposed aphrodisiac effects of ambergris. Although ambrein itself is odorless, it serves as the biological precursor for aromatic derivatives such as ambroxan and is thought to possess fixative properties for other odorants.
