1,3-Dioleoyl-2-stearoyl glycerol, also known as 1,3-Olein-2-stearin or TG(18:1/18:0/18:1), is a naturally occurring mixed triglyceride composed of two oleic acid chains (C18:1) at the sn-1 and sn-3 positions and one stearic acid chain (C18:0) at the sn-2 position of the glycerol backbone.
This compound has been identified and quantified in bovine milk fat, where it contributes to the overall triglyceride distribution, melting behavior, and functional properties of dairy lipids. It is widely used as a reference compound in lipidomics, food science, and fat composition research, particularly in studies focusing on milk fat structure and triglyceride profiling.
