Abstract

A compound may generally comprise the formula: wherein R 1 is independently selected from C 2 -C 10 alkyl or substituted alkyl, R 2 is independently selected from the group consisting of —H and C 1 -C 6 alkyl or substituted alkyl, X is selected from the group consisting of —NH— and —O—, Y is a carbohydrate, and m is an integer from 1 to 8. The compound may comprise a non-ionic acid labile surfactant. The compound may be used to facilitate solubilization of proteins and other molecules in an aqueous environment.
