Despite numerous studies on detergent-induced solubilization of membranes and on the underlying mechanisms associated with this process, very little is known regarding the selectivity of detergents for lipids during their extraction from membranes. To get insights about this phenomenon, solubilization of model bilayers prepared from binary lipid mixtures by different detergents was examined Three commonly used detergents were used: the non-ionic Triton X-100 (TX), the neg.-charged sodium dodecylsulfate (SDS), and the pos.-charged n-dodecyltrimethylammonium chloride (DTAC). Two model membranes were used in order to identify if specific intermol. interactions can lead to lipid selectivity: bilayers made of a binary mixture of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine (POPE), and of a binary mixture of POPC and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoglycerol (POPG). Therefore, it was possible to describe systems presenting a combination of detergents bearing different charges with bilayers with different polymorphic propensities and charge. In conditions for which partial solubilization was observed, the composition of the extracted lipid phase was quantified with Liquid Chromatog. coupled to Mass Spectrometry to elucidate whether a lipid selectivity occurred in the solubilization process. On one hand, it is found that repulsive or attractive electrostatic interactions did not lead to any lipid selectivity. On the other hand, POPE was systematically less extracted than POPC, regardless of the detergent nature. We propose that this lipid selectivity is inherent to the mol. shape of POPE unsuited for micelles curvature properties. This study involved multiple reactions and reactants, such as (2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate (cas: 26662-94-2Name: (2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate).
(2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate (cas: 26662-94-2) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Name: (2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate
