Resumen
Lauryl glucoside is a surfactant that exhibits self-assembly. Lauryl glucoside has relatively simple molecular structure of 12 carbons chains makes it easier to be simulated with molecular dynamics (MD) simulation. From previous study, it was found that the amount of water molecules plays an important role in the stability of intermolecular interaction between glucoside and water molecules. In this research, MD simulation was applied to discover the interaction of glucoside system in water by using COMPASS force field. The objective of this research is to study the stability effect of different number of water molecules on glucoside. The simulation was performed by using Material Studio (MS) software at 2 ns simulation time. From the trajectory output files, the Radial Distribution Function (RDF) were analysed. The simulation lead to a discussion of the effects of interaction between a single lauryl glucoside molecule and different number of water molecules, and the stability on the interaction between lauryl glucoside-water system. These finding also analysed the difference of simulation between lauryl glucoside and stearyl glucoside. It was found that lauryl glucoside possesses better intermolecular interaction based on its shorter distance and highest peak RDF analysis. Overall interaction explains that glucoside requires higher water molecules for better stability and good hydrogen bonding interaction.
