1,2,3-Tri-γ-linolenoyl glycerol, a polyunsaturated triacylglycerol featuring γ-linolenoyl side chains at the C-1, C-2, and C-3 positions, occurs in multiple plant species such as blackcurrant, redcurrant, and borage.
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.
