From Gut to Bloodstream: Unraveling the Digestive Fate of Iridoid Glycosides from Gaultheria Berries
Iridoid glycosides such as monotropein, abundant in Gaultheria berries, are promising bioactive compounds, yet their fate within the human body remains poorly understood. This presentation traces monotropein's digestive journey: uptake across the intestinal epithelium and transformation by gut microbiota and liver enzymes into novel catabolites, identified through advanced mass spectrometry. These findings, together with a dedicated bioanalytical method and an ongoing human bioavailability study, are building a comprehensive picture of how iridoids are absorbed, biotransformed, and may promote health.
Dr. Jiménez-Aspee completes the Habiltiation proceedings in the field of nutritional science with this inaugural lecture. Before, at 1:30 pm, PD Dr. Pablo Arauzo Gimeno, Dept. Conversion Technologies of Biobased Resources (440f), delivers his inaugural lecture on the subject of: From Biomass Residues to Functional Carbon Materials through Thermochemical Conversion.
