Palmitoleic acid is a common constituent of the triglycerides of human adipose tissue. Palmitoleic acid-based diets raise low-density lipoprotein cholesterol and diminish high-density lipoprotein cholesterol, even when dietary intake of cholesterol is maintained at a low level. Palmitelaidicacid is the trans isomer of the 16:1 fatty acid palmitoleic acid. While its effects on cholesterol levels are poorly studied, palmitelaidicacid can have very different effects from those of palmitoleic acid on lipid metabolism and mobilization. Palmitelaidicacid methyl ester is an ester version of the free acid which may be more amenable for the formulation of fatty acid-containing diets and dietary supplements.
Ricinelaidicacid is a 12-hydroxy fatty acid and an antagonist of leukotriene B4 (LTB4) receptors (Ki = 2 μM in porcine neutrophil membranes). It inhibits chemotaxis and calcium flux induced by LTB4 in isolated human neutrophils (IC50s = 10 and 7 μM, respectively). Ricinelaidicacid (1 mg/kg, i.v.) inhibits bronchoconstriction induced by LTB4 in rats by 46%.
1,2-Dielaidoyl-3-stearoyl-rac-glycerol is a triacylglycerol comprised of elaidicacid at the (sn-1) and (sn-2) positions, and stearic acid at the (sn-3) position.
1-Palmitoyl-2-elaidoyl-3-linoleoyl-rac-glycerol is a triacylglycerol composed of palmitic acid (at the sn-1 position), elaidicacid (at the sn-2 position), and linoleic acid (at the sn-3 position) respectively.
