Cerebrosides 22,7%MetaboliteCHEBI:23079 (ChEBI) Even though there are no absolute myelin-specific lipids, cerebroside, also known as galactosylceramide, is the most typical of myelin. The concentration of cerebroside in brain is directly proportional to the amount of myelin present. Cerebroside is not required for myelin formation but plays an important role in its insulating capacity and stability.
