;;;;;; Martini lipid topology for di-C20:4-C22:5 PA (DAPA)
;
; Description:
; A general model phosphatidic acid (PA) lipid corresponding to atomistic e.g. C20:4(5c,8c,11c,14c) di-arachidonic acid (AA),
; - C22:5(4c,7c,10c,13c,16c) docosapentaenoic acid tails.
; Parameterization:
; This topology follows the standard Martini 3 lipid definitions for building blocks. Further optimization in the bonded parameters are currently on development.
