myelin

Myelin is a dielectric, electrically insulating material of protein and fat that forms a layer, the myelin sheath, usually around only the axon of a neuron. Its composition is well specified: about forty per cent of myelin is water, and its dry mass is roughly seventy to eighty-five per cent lipids and fifteen to thirty per cent proteins. Among its constituent proteins are myelin basic protein, myelin oligodendrocyte glycoprotein, and proteolipid protein, while its primary lipid is a glycolipid, galactocerebroside. The intertwining hydrocarbon chains of sphingomyelin serve to strengthen the sheath. That lipid-dominated composition is the basis of its insulating property, since the material surrounds the axon rather than the cell body or dendrites.

A dielectric (electrically insulating) material consisting of protein and fat that forms a layer, the myelin sheath, usually around only the axon of a neuron. Myelin is about 40 % water; the dry mass of myelin is about 70 - 85 % lipids and about 15 - 30 % proteins. Some of the proteins that make up myelin are myelin basic protein (MBP), myelin oligodendrocyte glycoprotein (MOG), and proteolipid protein (PLP). The primary lipid of myelin is a glycolipid called galactocerebroside (GalC). The intertwining hydrocarbon chains of sphingomyelin serve to strengthen the myelin sheath.
