A new set of general parameter building blocks was designed to fit the updated mapping scheme. Bond lengths now take the modified bead sizes into account and account for whether bonded beads span multiple double bonds, found to have an impact on the average bond length (adjacent double bonds make the center-ofgeometry distance between beads shorter). While Martini 2 and Martini v3.0.0 use specific angles over beads containing double bonds (i.e. C-D-C where D is a bead containing a double bond), there is no differentiation between angles where the adjacent beads contain double bonds (e.g. D-D-C or D-D-D) . Our atomistic reference simulations of polyunsaturated lipids suggest that the angle distribution varies depending on the number of double bonds in the lipid tails, and the CG angles were diversified to account for multiple unsaturated beads connected in series. In the new parameter set these cases are fitted independently, improving the angle distribution fit of mono-and polyunsaturated lipids.
