1,2,3-Tripalmitoleoyl-rac-glycerol is a triacylglycerol containing palmitoleic acid at the sn-1, sn-2 and sn-3 positions. It reduces erythrocyte deformability in a concentration-dependent manner in the Reid filtration assay. Hepatic levels of 1,2,3-tripalmitoleoyl-rac-glycerol are increased in a JAK2L mouse model of hepatic steatosis. 1,2,3-Tripalmitoleoyl-rac-glycerol plasma levels are reduced in patients with predialysis renal disease.
