Abstract:

A new method of screening between two mannose isomeric derivatives, based onmass spectra (EI-GC-MS) analysis and their correlation with heats of formation estimated from semi-empirical calculations, is presented. The heats of formation for some main fragments, selected from the analyzed compounds mass spectra, were calculated with HyperChem and MOPAC software using semi-empirical methods (AM1, MINDO3, MNDO, RM1, PM3 and PM7) in trying to explain the difference between peak intensities
obtained experimentally. These glycoderivatives can find multiple applications as biocompatible and biodegradable surfactant precursors in fields like pharmacy, medicine and biotechnologies.
