The ubiquitous occurrences of glycans (from oligo to polysaccharides) as cell components to significant constituents of the terrestrial biomass provide the glycans with a panel of biological functions and physicochemical properties. The progress made in algorithms and computational power allows for the simulation of glycans in their natural environment, and new dimensions, both spatial and temporal, can be assessed. The review will illustrate advancements in high-performance computing have allowed molecular simulation methods not only to play a more substantial role in supporting experiments but to transcend such mandate to guide experimental design and to lead autonomously scientific discovery.
