Structural characterization of self-assemblies of new omega-3 lipids: docosahexaenoic acid and docosapentaenoic acid monoglycerides.

The attractiveness of new omega-3 (ω-3) polyunsaturated fatty acid (PUFA) monoglycerides (MAGs) lies in the amphiphilic nature and the beneficial health effects as PUFA precursors in various disorders including cancer, pulmonary hypertension, and inflammatory diseases. For exploring the potential therapeutic applications of these new amphiphilic lipids, particularly as main lipid constituents in the development of nanocarriers for delivery of drugs and PUFAs, it is of paramount importance to gain insight into their self-assembly behavior on exposure to excess water. This work describes the structural characteristics of self-assemblies based on two newly synthesized MAGs, namely docosahexaenoic acid (MAG-DHA) and docosapentaenoic acid (MAG-DPA) monoglycerides, on exposure to excess water.
