Fatty acid composition of glycerides and stereospecific analysis of triglyceride in pea seeds.

Abstract

Pea seeds were shown to contain ten kinds of neutral lipids, among which triglyceride, free sterol and sterolester are the main components and diglyceride, monoglyceride, free fatty acid, wax and some pigments are the minor ones. The major component fatty acids in the glycerides and the free fatty acid are C18:2, C18:1 and C16:0. The positional distribution of fatty acids in triglyceride is such that, position 1 and 3, especially the former, abound in saturated fatty acids, and position 2 is filled almost entirely with unsaturated fatty acids.
