1,2-Dipalmitoyl-3-decanoyl-rac-glycerol, a triacylglycerol, comprises palmitic acid at the sn-1 and sn-2 positions and decanoic acid at the sn-3 position. This compound is present in bovine milk fat.
1-Palmitoyl-d9-2-palmitoyl-sn-glycerol serves as an internal standard for quantifying 1,2-dipalmitoyl-sn-glycerol using GC or LC-MS techniques. This diacylglycerol, featuring palmitic acid at both the sn-1 and sn-2 positions, stimulates protein kinase C (PKC) activity by 15% at a 25 μM concentration. Additionally, 1,2-dipalmitoyl-sn-glycerol encourages rapid growth in Frankia, a genus of Gram-positive bacteria.
1,2-Dipalmitoyl-3-myristoyl-rac-glycerol, a triacylglycerol, incorporates palmitic acid at the sn-1 and sn-2 positions, along with myristic acid at the sn-3 position, and is identified in bovine milk fat.
1,2-Dipalmitoyl-3-linoleoyl-rac-glycerol, a triacylglycerol, features palmitic acid at the sn-1 and sn-2 positions and linoleic acid at the sn-3 position. This compound is present in ostrich and emu oils as well as in bovine milk fat.
