This episode features exclusive interviews collected at the 2022 MetSoc conference in Valencia, Spain. Across these recordings, you will hear about the polar metabolites and the lipids that make the hearts of fourteen Metabolomists beat for their research. In this special episode, we learn more about pyruvate, gamma-hydroxybutyric acid (GHB), glutathione, branched-chain alpha keto acids (BCKAs), tryptophan, glutamine, glutamate, nicotinamide adenine dinucleotide (NAD), nonanal, strychnine, daptomycin, but also free fatty acids, oxylipins, sphingolipids, and acylcarnitines. A big thank you to all the contributors! Make sure to let them know that you share their passion for their favorite metabolite by connecting with them with the links below.
