A molecular dynamics investigation of the helical forms adopted by (1→4)‐α‐L‐guluronan in explicit water environment was carried out. Single chains and duplexes were modeled at 300 K starting both from 21 or 32 helical conformations and in the presence of a neutralizing amount of Ca2+ ions. All systems were allowed full conformational freedom. The initial perfect helices with integral screw symmetries...
In order to model the adsorption of xylan on cellulose, we have simulated, at the atomic level, the gas phase adsorption of small xylan fragments having 5 skeletal β (1 → 4) xylosyl residues (X5), using molecular dynamics simulations. A first regime was considered, corresponding to a low surface coverage, with the adsorption of isolated X5 in various initial orientations. In this regime, the simulation...
The present study provides a theoretical description of the different levels of structural organization that characterize the xylan polysaccharide in its native and hydrophobic lauroyl esterified forms. The goal of this study was to ascertain the role played by the hydroxyl or lauroyl side groups on the conformational flexibility of the xylan chain backbone. The results reported provide a detailed...
