The present invention relates to cationic lipids. More particularly, the present invention relates to biodegradable cationic lipids having a plurality of cationic head groups and one or more lipophilic end groups. Lipids are useful for enabling various uses, particularly transfection of molecules, particularly DNA and RNA, into cells. As such, lipids are of particular use not only in the field of gene therapy but also in other applications such as delivery of small molecules into cells, surfactants, and metal ion complexation in medical or industrial applications.
