Steryl glucosides are neutral glycolipids commonly found in plant cell membranes and vegetableoils that contain a glucose moiety conjugated to a sterol lipid. They function as glucose donors in the biosynthesis of glucocerebrosides in plant microsomes and are metabolic precursors to acylated esterified steryl glucosides. Steryl glucosides are the major component of filter- and engine-damaging precipitates formed during biodiesel production from transesterification of vegetableoils. This product contains a mixture of steryl glucosides.
POL, a prevalent triglyceride component in various seed and vegetableoils such as olive, sesame, soybean, canola, corn, and hazelnut, is standardly utilized in the USP analysis of sesame oil for pharmaceutical applications.
1-Myristoyl-2-linoleoyl-3-palmitoyl-rac-glycerol, a triacylglycerol comprising myristic, linoleic, and palmitic acids at the sn-1, sn-2, and sn-3 positions respectively, is present in palm and vegetableoils.
1,2-Dilinoleoyl-3-palmitoyl-rac-glycerol is a triacylglycerol featuring linoleic acid at the sn-1 and sn-2 positions and palmitic acid at the sn-3 position. Present in various vegetableoils such as poppy seed, hazelnut, maize, and olive, this compound (3% w v) effectively reduces scald development in Delicious apples when applied right after harvest, with results observed after six months of storage.
1,2-Dioleoyl-3-linoleoyl-rac-glycerol (OOL) is a triglyceride featuring oleic acid at the sn-1 and sn-2 positions and linoleic acid at the sn-3 position. This compound is prevalent in several seed and vegetableoils, such as those from pumpkin seeds, olives, and sesame.
1,2-Distearoyl-3-oleoyl-rac-glycerol, a triacylglycerol, comprises stearic acid at the sn-1 and sn-2 positions and oleic acid at the sn-3 position. This compound is present in cocoa butter and vegetableoils.
