C(O)— (5),
wherein:
each R
5
is independently an optionally substituted C
1-4
alkylene moiety; and
R
3
is an optionally substituted alkylene or alkenylene moiety; and
(iii) two lipophilic moieties,
wherein the head group and each of the lipophilic moieties are connected to the linking moiety through amide linkages.
