Mutating a lipid means changing its chemical structure. We do this when our membrane contains a lipid which is not available by default in the CHARMM force field, but the structure is similar to an existing lipid. To mutate a lipid, you'll need to create your membrane with the pre-mutated lipids using CHARMM-GUI first. | Mutating a lipid means changing its chemical structure.

For small mutations, the IC table isn't necessary. \\ | + | Once that is done, modify the relevant .str file to include your mutated lipid.
