While the role of the gut microbiota is already confirmed as pivotal in food and drug metabolism, the specific biological influence of these metabolic pathways—particularly those involving olive oil and bilberries—remains largely unexplored. The aim of my project, DC11, is to bridge the gap between the molecules we ingest and those that actually exert a therapeutic effect on our health. To achieve this, I will use state-of-the-art synthetic methods to generate high-purity analytical standards. These pure molecules will be crucial for the structural elucidation of food metabolites, serving as indispensable references for both bioanalytical quantification (in clinical samples like plasma, urine, and feces) and subsequent biological assays across the network.
