Summary
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.
2. Laballenic acid esterifies all three positions, with a preference for the extreme ones, in the triacylglycerol ofPh. regelii M. Pop.
3. The phosphorylation of the sn-1,2- and sn-2,3-diacylglycerols is not accompanied by the formation of appreciable amounts of by-products when previously cooled reagents are used.
