Peter Delannoy discusses the metabolic pathways involving fructose and glucose, focusing on the "survival switch" mechanism that includes enzymes such as glucokinase, aldose reductase, fructokinase, and phosphofructokinase. He explains how these pathways influence metabolic disease development, particularly through the activation of fructose uric acid metabolism. The talk covers the biochemical reactions, including glycolysis and the polyol pathway, and their impact on liver function, mitochondrial health, and insulin resistance.
