Abstract: This study was conducted to determine why 1,2-; 2,1-and 1,2-; 1,3-positional isomers of diacyl glycerolipids, including those that are depolarized, are separated on reverse phase HPLC while triglycerides are not. Interaction forces among the carbon chains of lipid molelcules generated by the Coulomb force of atoms were concluded to be stereochemically well balanced in the case of triglycerides in contrast to diacyl glycerolipids. Possibly, the larger the acyl carbon number, the greater is the lack of conformity of interaction forces among acyl moieties. This is a factor determining the chemical potential of lipid molecules and gives rise to small but reproducible differences in retention on reverse phase HPLC between the 1,2-and 2,1-as well as 1,2-and 1,3-positional isomers.
リン脂質の誘導体を含むジアシルグリセロ脂質の1,2-;1,3位置異性体がODS系逆相クロマトグラフィーでは分離されるのに対して,トリアシルグリセリンではそれらの分離が困難である理由について考察した。その結果,クーロン力の反発によるアシル基間の相互作用のバランスがトリアシルグリセリンではよいのに対して,ジアシル型脂質ではこのバランスがわるく,炭素鎖がのびるほどこの傾向が強くなり,クロマト系における化学ポテンシャルにも影響を与えて1,2-;1,3-位置異性体が分離されるものと結論した。
