cerebroside
Quick Summary
Cerebrosides are a type of glycolipid, which are a subclass of sphingolipids. These lipids are characterized by the presence of sphingosine, an amino alcohol. Cerebrosides are particularly abundant in the myelin sheath that surrounds nerve cells. They are composed of a ceramide (sphingosine linked to a fatty acid) and a single sugar molecule, such as glucose or galactose. The name "cerebroside" itself is derived from "cerebrose," referring to galactose. These compounds play a role in nerve tissue and are found in small amounts in plant and animal tissues. Abnormalities in sphingolipid metabolism, including that of cerebrosides, can lead to various diseases known as sphingolipidoses, such as Tay-Sachs disease.12
