are, the same or different, alkenyl, etc, and
X
1
and X
2
are hydrogen atoms, or are combined together to form a single bond or alkylene, and
X
3
is absent or is alkyl, etc,
Y is absent or anion,
a and b are, the same or different, 0 to 3, and
L
3
is a single bond, etc,
R
3
is alkyl, etc,
L
1
and L
2
are —O—, —CO—O— or —O—CO—),
a composition comprising the cationic lipid and a nucleic acid, and
