Hi,

Actually, in CHARMM DPPC is built from PALM and PCGL residues:

RESI PCGL 0.00 ! glycerolphosphorylcholine
                        ! nomenclature for creation of DPPC
                        ! from PALM and PCGL via patches EST1 and EST2

That macro contains "PGCL" instead, which may just be a typo. Adding DPPC
is probably a good idea as well.
