Glycans have an immense number of biological activities, necessitating increased efforts to characterize glycan structures. Mass spectrometry has been coupled to electrospray ionization (ESI) to characterize carbohydrates. While the gas-phase structures of glycan- and carbohydrate-metal adducts have been characterized, several questions persist concerning the mechanism of transfer of carbohydrates from ESI droplets into the gas phase. Using various computational methods, including molecular dynamics, steered molecular dynamics, and density functional theory calculations, we present a mechanistic investigation on the evaporation of solvent from nanosized droplets, formation of carbohydrate-metal adducts, and their subsequent release into the gas phase. We relate the computational results to mass spectra of melezitose, a model carbohydrate, and its permethylated derivative. Our results confirm two mechanisms for the release of carbohydrate-ion adducts from solvated droplets. Native (unmodified) carbohydrates are ionized via the charged residue model, while the permethylated derivative is ionized via the ion evaporation model. For both mechanisms, the monomer carbohydrate-metal adduct is the dominant species observed. This work illustrates that the ionization mechanisms are dictated by interactions between the carbohydrate and solvent, and coordination of the carbohydrate with the metal ion. Thus, these results provide insight into the molecular interactions that govern the mechanism of release.
