Figure 2

United atom and coarse-grained representations of (a) DSPS and (b) 21PC. The color scheme is black (negatively charged carboxyl group, type Ia; protonated carboxyl group, type Ib for DSPS site 1); magenta (amine group, type II for DSPS site 2); yellow (phosphate group, type III for DSPS site 3); red (ester group, type IV for DSPS site 4 and 21PC site 3); orange (ester group, type V for DSPS site 11 and 21PC site 11); cyan (alkyl tail groups, type VI for DSPS sites 5–9 and 12–16 and for 21PC sites 4–9 and 12–17); gray (terminal tail groups, type VII for DSPS sites 10 and 17 and for 21PC sites 10 and 18); purple (choline entity, type VIII for 21PC site 1); and yellow (phosphate group, type IX for 21PC site 2).
