The association of anionic surfactants with β -cyclodextrin. An isothermal titration calorimeter study

Application of ITC in foods: A powerful tool for understanding the gastrointestinal fate of lipophilic compounds

“…Traditionally, ITC has been used to study highly specific protein-protein or protein-small molecule interactions, however, there is increasing interest in using it to analyze more complex systems. For example, ITC has been used to measure enthalpy changes associated with interactions in colloidal systems, such as dissociation of surfactant micelles [26][27][28], binding of surfactants to polymers [29][30][31], adsorption of surface-active molecules to colloidal particles [32][33][34], and partitioning of molecules in aqueous micellar solutions [35,36]. In addition, ITC has previously been used to monitor enzyme hydrolysis reactions [37][38][39], which may be useful for studying the digestion of food components (such as proteins, carbohydrates, and lipids) under simulated GIT conditions.…”

Study of inclusion complexes of cycloamylose with surfactants by isothermal titration calorimetry

“…The negative value may be due to the decrease in conformational flexibility of the CA chain when SDS penetrates into the cavities of CA. For the complexation of CA and DTAB, since DTAB penetrated CA cavity further than SDS, a larger number of water molecules to the bulk solvent were released and thus this factor could explain less negative and positive entropy of CA and DTAB complexation (Eli & Chen, 1999;Sun et al, 2006). As mentioned above, the CA used in our study was composed of various DPs ranging mainly from 24 to 44.…”

Chitosan: A Multifunctional Polymer

“…The cyclic oligosaccharides, namely α-, β-, γcyclodextrins (CD), are important because of their ability to encapsulate hydrophobic molecules in their toroidal hydrophobic cavity, whose selectivity depends on the number of glucose units (respectively 6, 7, 8 D-glucose units) [92][93][94]. For various applications, it is interesting to graft the cyclodextrin on a polymeric backbone such as a biocompatible polysaccharide.…”
