Bioactivity: 1-Oleoyl-2-palmitoyl-rac-glycerol (1,2-OP) is a diacylglycerol containing oleic acid at the sn-1 position and palmitic acid at the sn-2 position. It enhances the inhibition of superoxide anion production by cytochalasin B when used at a concentration of 10 μM. The concentration of 1,2-OP decreases from 25.7 to 11.15% during the dry-curing process of Iberian ham.
