PG(18:1(9Z)/18:1(9Z)) is a lipid of Glycerophospholipids (GP) class. Pg(18:1(9z)/18:1(9z)) is associated with abnormalities such as Neonatal hemochromatosis, Renal tubular disorder, Hereditary pancreatitis and UDPglucose 4-epimerase deficiency disease. The involved functions are known as Genetic Translation Process, Regulation, Saturated, enzyme activity and Cytokinesis. Pg(18:1(9z)/18:1(9z)) often locates in Membrane, soluble, Tissue membrane, membrane fraction and Thylakoid Membrane. The associated genes with PG(18:1(9Z)/18:1(9Z)) are COIL gene, P4HTM gene, GRAP2 gene, Integral Membrane Proteins and synthetic peptide. The related lipids are Liposomes, Fatty Acids, Sphingolipids, DOPE and 1,2-oleoylphosphatidylcholine.
