Sphingomyelin (SM, ) is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath that surrounds some nerve cell axons. It usually consists of phosphocholine and ceramide, or a phosphoethanolamine head group; therefore, sphingomyelins can also be classified as sphingophospholipids. In humans, SM represents ~85% of all sphingolipids, and typically makes up 10–20 mol % of plasma membrane lipids.
