1,2,3-Tri-13(E)-docosenoyl glycerol, a triacylglycerol featuring 13(E)-docosenoic acid at the \(sn-1\), \(sn-2\), and \(sn-3\) positions, transiently elevates heart triglyceride levels in weanling rats when administered as 15% of a calcium-deficient diet, with levels returning to baseline after 28 days.
1,2,3-Tri-11(Z)-eicosenoyl glycerol, a triacylglycerol with 11(Z)-eicosenoic acid at the sn-1,sn-2, and sn-3 positions, serves as an internal standard for quantifying triacylglycerols in seed and olive oils.
