percentage of cholesterol in myelin sheath
Many glial cells lined up along an axon are required to fully myelinate and insulate a long nerve cell. The composition of myelin is approximately 30 percent protein, 27 percent cholesterol and 43 percent phospholipid.Myelin production is absolutely dependent on cholesterol synthesis in the glial cells.n your brain and nerve tissue, cholesterol is required for the formation of the myelin sheath, a fatty material that surrounds long portions of nerve fibers. Myelin insulates nerve cells and enhances the passing of electrical signals throughout your nervous systemâs circuitry.
