In this work, we successfully develop and validate a Martini 3 CG model of cholesterol. Our goal with this effort was not just to revisit and update the previous model 96 to the Martini 3 framework 16 , but also to address issues pertaining to the previous model. A compromise was made to address some of these points while maintaining or improving the characteristics of the previous model as much as possible. A more refined description of the mapping and bead types led to an improved hydrophobicity and interaction landscape, refining cholesterol interactions with other partners and reducing possible model stickiness. Cholesterol shape and volume were improved, yielding better packing in lipid bilayers and good crystal packing. The artificial temperature gradients due to convergence issues with the LINCS algorithm were solved while maintaining phase separation properties in line with the Martini 2 model and experimental data. Overall, this model is another step in the evolution of the already successful Martini 2 cholesterol model. We foresee iterative improvements in both the Martini 3 phospholipid models and the interaction matrix in the near future, which should impact in a more accurate description of phase diagrams of ternary mixtures like DPPC:DOPC:CHOL.
