1,2-Dioleoyl-3-α-linolenoyl-rac-glycerol is a triacylglycerol that contains oleic acid at the sn-1 and sn-2 positions and α-linolenic acid at the sn-3 position. It has been found in the fat body of male B. lapidarius bumblebees.¹

1,2-Dioleoyl-3-α-linolenoyl-rac-glycerol (1,2-Olein-3-α-linolenin) is a compound that is being studied as a triglyceride in bumblebee fat body. Chromatographic analysis revealed differences in fatty acid composition and triglyceride isomer distribution in different bumblebee species.
