ABSTRACT:
The present invention provides a novel complex lipid having a cationic functional group derived from an amino acid. Namely, the present invention provides a cationic acid amino acid type lipid represented by the following formula:wherein, R1is a hydrocarbon group having a cationic functional group derived from an amino acid, R2and R3are each independently a chain hydrocarbon group, A1and A2are each independently a linkage group selected from the group consisting of —COO—, —OCO—, —CONH— and NHCO—, and n is an integer of 2 to 4.
