12-Dipalmitoyl-3-Linoelaidoyl-rac-glycerol is a triacylglycerol containing palmitic acid in the sn-1 and sn-2 positions and linolelaidic acid in the sn-3 position. Palmitic acid is a long-chain saturated fatty acid commonly found in animals and plants, capable of inducing the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer-binding protein homologous protein (CHOP) in mouse granulosa cells. Linolelaidic acid, an omega-6 trans fatty acid (TFA), serves as an energy source and is an essential nutrient that can be incorporated into enteral, parenteral, and infant formulas. Additionally, linolelaidic acid is utilized in heart disease research.
