Electric Biochemistry of Sphingomyelin

Sphingomyelin is a major phospholipid in myelin sheaths, which play a pivotal role in saltatory,conduction of myelinated axons [1]. Sphingomyelin consists of phosphorylcholine or phosphoryl ethanol amine and ceramide [2] to form lipid bilayer of cell membrane [3]. Under the physiological condition at neutral pH, choline is a positive residue, which associates with an anion such as a chloride ion Phosphate forms diester bonds with
