steryl glucosides

Steryl glucosides are neutral glycolipids commonly found in plant cell membranes and vegetable oils 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 vegetable oils. This product contains a mixture of steryl glucosides.
