    摘要： An object of the present invention is to provide a lipid composition making it possible to achieve excellent delivery of nucleic acids. According to the present invention, there is provided a lipid composition containing a lipid represented by Formula (1) or a salt thereof, a nonionic lipid, a lipid having a nonionic hydrophilic polymer structure, and a nucleic acid, in which the lipid composition contains or does not contain a zwitterionic lipid, and in a case where (A) represents a molar ratio in percentage of the lipid represented by Formula (1) or a salt thereof to total lipids constituting the lipid composition and (B) represents a molar ratio in percentage of the zwitterionic lipid to total lipids constituting the lipid composition, (A) and (B) satisfy 40
    In the formula, X represents -NR 1 - or -O-, R 1 represents a hydrogen atom, a hydrocarbon group, or the like, R 2 and R 3 each independently represent a hydrogen atom, a hydrocarbon group, or the like, R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , and R 12 each independently represent a hydrogen atom or an alkyl group, groups in any one or more pairs among R 4 and R 5 , R 10 and R 5 , R 5 and R 12 , R 4 and R 6 , R 5 and R 6 , R 6 and R 7 , R 6 and R 10 , R 12 and R 7 , and R 7 and R 8 may be linked to each other to form a 4- to 7-membered ring which may contain an O atom, a, b, c, and d are each independently represent an integer of 0 to 3, a + b is 1 or more, and c + d is 1 or more.

    摘要： An object of the present invention is to provide a lipid composition capable of achieving excellent nucleic acid delivery for a wide variety of nucleic acids. According to the present invention, there is provided a lipid composition containing a first lipid which is a lipid represented by Formula (1) or a salt thereof, sterols, and nucleic acid, in which a ratio of the number of moles of the first lipid in the lipid composition to the number of moles of sterols in the lipid composition is 0.300 or more and less than 1.299.

    In the formula, X represents -NR 1 - or -O-, R 1 represents a hydrogen atom, a hydrocarbon group, or the like, R 2 and R 3 each independently represent a hydrogen atom, a hydrocarbon group, or the like, R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , and R 12 each independently represent a hydrogen atom or an alkyl group,
    groups in any one or more pairs among R 4 and R 5 , R 10 and R 5 , R 5 and R 12 , R 4 and R 6 , R 5 and R 6 , R 6 and R 7 , R 6 and R 10 , R 12 and R 7 , and R 7 and R 8 may be linked to each other to form a 4- to 7-membered ring which may contain an O atom, a, b, c, and d are each independently represent an integer of 0 to 3, a + b is 1 or more, and c + d is 1 or more.
