Interfacial properties of surfactants are dependent on the conformation adopted by the hydrophilic headgroup or/and the hydrophobic tail at the boundary limit of two immiscible phases. Here, we demonstrate the impacts of the carbonyl group (-CO-) location of the ester bond of sugar-based surfactants by comparing some properties of two closely related esters, octyl glucuronate and glucose octanoate, at the air-water interface. The carbonyl group location influences the rate and extent of interfacial adsorption and the rheology properties of sugar esters at the air-water interface, which were evaluated by dynamic surface tension and complex surface viscoelastic measurements. Octyl glucuronate adsorbs the fastest at the air-water interface whereas glucose octanoate reduces the dynamic surface tension at the lowest value and exhibits the highest film viscoelasticity. Differences are attributed to molecular conformation constraints inducing relevant changes to the surface coverage kinetic capacity and the interaction strengths of the octyl sugar ester adsorbed films at the air-water interface. All of the results are supported by the minimum cross-sectional area values per molecule determined by both experimental and computational approaches. [less ▲]

Lipases are able to catalyse the hydrolysis of glyceridic esters in aqueous media and the synthesis of esters in non-aqueous media. They are thus able to catalyse numerous reactions of industrial interest. Whether it is by inclusion, by adsorption or by covalent link, the immobilisation of lipases aims at conferring them a good stability that enables a reuse of the enzymes after a reaction and the development of continuous processes. The reactions of triglycerides hydrolysis constitute main applications for immobilised lipases, however their use in different types of esterification reactions has also arose: there exist processes involving reactions of transesterification, of interesterification or of esters synthesis. The production of structured lipids by interesterification is one example. Although the reaction conditions dissent from those of hydrolysis, the same lipases have been used in both cases. A lipase specifically adapted for esterification though would be a highly capable tool: a series of strategies is in progress in order to reach this goal. [less ▲]

A simple and rapid procedure was cl developed for the extraction of the milk fat globule membrane from milk removes the large majority of the skim milk proteins for proteome analysis. In order to improve the extraction and the solubilization of the hydrophobic membrane proteins for subsequent two-dimensional gel electrophoresis, four detergents (3-[(3-cholamidopropyl)dimethylammoniol-1-propanesulfonate, amidosulfobetaine-14, sodium lauroyl sarcosinate and sodium deoxycholate) were tested in the sample preparation, associated with a sonication step. Zwitterionic detergents were shown to be efficient in recovering integral and peripheral proteins from membrane material. Spots were identified by matrix-assisted laser desorption/ionization tandem-time-of-flight (MALDI-TOF/TOF). The advantages of MALDI-TOF/TOF (speed, easiness of analysis, good sensitivity and high mass accuracy) were demonstrated on the milk fat globule membrane proteome investigation. Identified proteins are implicated in a wide range of functions including fat secretion and transport, protein trafficking and regulation. (C) 2008 Elsevier Ltd. All rights reserved. [less ▲]
