Exemplary lipid from each of the identified clusters taken from the 512 lipid, 315 K simulation. A linear-ordered lipid (A), disordered lipid (B), splayed-ordered lipids (C), and splayed-disordered lipids (D). The corresponding distributions of the atoms in these individual lipids are also shown. (E), (F), (G), and (H) correspond to (A), (B), (C), and (D), respectively. The first gauche defect peaks (up and down tail) are marked with arrows, and the contribution of the other tail peak is marked with an arrow for clarity. To see this figure in color, go online.
