For example, during the recent pandemic, the first structures of the Spike protein of the SARS-parameterization of more complex saccharides. In total we present parameters for 42 disaccharides, including details of the parameterization protocol. All of the bonded parameters were derived from reference atomistic trajectories, whereas the non-bonded parameters (bead type assignment) and mapping correspond to the already validated Martini 3 monosaccharides. 70% of the systematically built disaccharides were parameterized via a fully automated approach. Where full automation is not currently possible, we provide details of the manual parameterization protocol.
