DOPC, or 1,2-dioleoyl-sn-glycero-3-phosphocholine, is a common phospholipid used in membrane research. As a lipid, it is important for the formation of lipid bilayers in cells that help protect and maintain cellular homeostasis. Synonyms for DOPC can include 1,2-diacyl-sn-glycero-3-phosphocholine, dioleoylphosphatidylcholine, and cis-9,10-epoxyoctadecenoic acid 1,2-dioleoyl-sn-glycero-3-phosphocholine ester. Researchers may also refer to it as simply phosphatidylcholine or PC, which is the general class of phospholipids to which DOPC belongs.
