The Brazilian Symposium of Theoretical Chemistry is a traditional event covering all aspects of molecular physics and theoretical chemistry. This includes quantum chemistry as well as computer simulation and modeling. In some recent years, following a world tendency, there has been an increase in the study of biomolecular systems with emphasis on biomolecular properties , reactivity , structure and function in aqueous environment , the natural solvent. In this special issue some interesting investigations on biomolecules (such as amino‐acids , lipids and membranes ) are reported using quantum chemical calculations, classical simulations and also a combination of the two methods.
