Polarizable AMOEBA force field predicts thin and dense hydration layer around monosaccharides

Abstract

Polarizable force fields crucially enhance the modeling of macromolecules in polar media. Here, we present new parameters to model six common monosaccharides with the polarizable AMOEBA force field. These parameters yield a thinner, but denser, hydration layer than that previously reported. This denser hydration layer results in eliminating non-physical aggregation of glucose in water—an issue that has plagued molecular dynamics simulations of carbohydrates for decades.
