Mass spectrometric study of the dissociation of Group XI metal complexes with fatty acids and glycerolipids: Ag2H+ and Cu2H+ ion formation in the presence of a double bond

Lipids are important molecules that play a large role in biological systems. For example, triacylglycerols (TG) are involved in longterm energy storage and may also be linked to the cytotoxicity and dysfunction of pancreatic islet beta cells [1–3]. Glycerophospholipids (GPs) provide many biochemical functions due to their structural diversity. As well as providing structural support to cells, membrane phospholipids are the source of arachidonic acid, which is required for the formation of lipid mediators [4]. They also provide the precursors for platelet-activating factor molecules, and signaling molecules such as inositol triphosphate and diacylglycerol [4].
