My main work is orientated on the identification, structural elucidation and quantification of a variety of Lipid classes as well as their oxidized counterparts. Due to the high chemical and biophysical complexity of the different lipid classes plus their increasing complexity of their oxidation products (A) analysis by Liquid Chromatography coupled to Tandem Mass Spectrometry is challenging. (B)
The role of these lipid species in the development and progression of metabolic diseases related to obesity, such as type 2 diabetes and the metabolic syndrome is not yet fully understood. For this purpose the acquired data is put into a systems medicine environment to achieve a broader view on their functions.
Furthermore I am trying to understand the chemical and biophysical mechanisms of oxidation in lipid droplets (C) which are the main constituent of adipocytes in adipose tissue. Non-enzymatic lipid peroxidation is based on an oxygen-centered radicals (e.g. hydroxyl radical) which cannot penetrate through the outer LDs phospholipid monolayer indicating that other mechanisms of radical reactions might govern generation of oxidized lipids in LDs, either involving longer lived, hydrophobic organic radicals or radical propagation from PL monolayer into the LD core.
