Usage

General Description

1,3-Palmitin-2-Linolein is a chemical compound composed of two fatty acid molecules, palmitic acid, and linoleic acid, esterified to a glycerol molecule. Palmitic acid is a saturated fatty acid, while linoleic acid is an omega-6 polyunsaturated fatty acid. 1,3-Palmitin-2-Linolein? is commonly found in natural fats and oils, such as animal fats, vegetable oils, and nuts. It is a major component of triglycerides, which are the main form of dietary fat in humans. 1,3-Palmitin-2-Linolein has various physiological effects in the body, including energy storage, insulation, and cell membrane structure. It is also important for the absorption of fat-soluble vitamins and for maintaining overall health.

Regioisomeric characterization of triacylglycerols using silver-ion HPLC/MS and randomization synthesis of standards

Silver-ion normal-phase high-performance liquid chromatography (HPLC) provides a superior separation selectivity for lipids differing in the number and position of double bonds in fatty acid chains including the resolution of triacylglycerol (TG) regioiso

Practical syntheses of triacylglycerol regioisomers containing long-chain polyunsaturated fatty acids

Docosahexaenoic acid (DHA, 22:6n-3) is known to protect against a range of degenerative disease conditions and aid in the development of eye and brain function in infants. In dietary lipids DHA is found primarily in the triacylglycerol (TAG) form. However, the effects of the positional distribution of DHA in TAG on lipid functional properties such as bioactivity and oxidative stability are not clearly understood. Studies on this subject for the most part are limited by a lack of regioisomerically pure TAG model compounds containing DHA or similar long-chain (LC)-polyunsaturated fatty acids (PUFA). This paper reports on the development of a practical procedure, based on chemical and enzymatic reactions, for the syntheses of regioisomerically enriched, symmetrical and unsymmetrical TAG isomers containing two palmitic acid and one of linoleic acid, linolenic acid, or DHA. 1,3-Selective acylation of glycerol with vinyl esters of fatty acids catalyzed by Candida antarctica lipase and direct coupling with fatty acids in the presence of the coupling agents 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 4-dimethylaminopyridine furnished 1,3-dihexadecanoyl-2-docosahexaenoyl glycerol and its unsymmetrical isomer 1,2-dihexadecanoyl-3-docosahexaenoyl glycerol in 99 and 60% yield, respectively. Critical to the success of the unsymmetrical TAG synthesis is the demonstration that PUFA-containing glycerol acetonides can readily survive appropriately tailored acid-catalyzed conditions. In this way, sufficient quantities of highly regioisomerically enriched PUFA-containing unsymmetrical monoacylglycerols (MAG) and TAG have now become routinely accessible. The methods are amenable to scale-up and could be adopted for regioenriched synthesis of a wide range of TAG. AOCS 2007.
