CARDIOLIPIN METABOLIC PATHWAY (PW:0001344)

View Ontology Report

Description

Cardiolipin (CL) is considered the signature phospholipid of the inner mitochondrial membrane (IMM) which is also the site of its synthesis. Structurally, CL is a lipid dimer with two phosphatidyl groups connected by a glycerol backbone. It has two chiral carbons and four fatty acyl chains, usually polyunsaturated. It can interact with various proteins that include components of the electron transport chain (ETC), enzymes and metabolite carriers. CL is found in the crystal structures of complex
