A study of the structure of plant triacylglycerols by the method of stereospecific analysis

1. In the triacylglycerols of the seeds of three species of the family Labiatae, the saturated acids are distributed either predominately in the sn-1 position or in the sn-1 and sn-3 positions; the distribution of the 18 : 1 acid is characteristic for each oil; the 18 : 2 acid esterifies mainly the sn-2 position and of the two extreme positions, the sn-1; the 18 : 3 acid in two species occupies predominantly the sn-3 position and in one species predominantly the sn-1 position.
