Abstract
In this work we use the Enforced Geometry Optimization (EGO) approach to simulate force-induced structural changes in the monomer, and di- up to pentameric oligomers of neutral and non-sulfated carrageenan based oligosaccharides. Our results indicate that the monosaccharide unit sequence in the oligomeric structure determines: (i) the type(s) of the enforced conformational transition(s), and (ii) the mechanical resistance to external forces. It is a direct consequence of the different glycosidic bonding types in the examined carregeenan based oligosaccharides.
