Pyruvate kinase-mediated (PKM) PEP-to-pyruvate conversion reveals dual metabolic fate: pyruvate dehydrogenase (PDH)-dependent acetyl-CoA production for TCA cycle entry versus lactate dehydrogenase (LDH)-driven lactate (LA) generation, epitomizing the Warburg phenotype

GLP-1 stands for glucagon-like peptide-1, which is a hormone that helps slow digestion and reduce food cravings

TL;DR: The GLP-1 receptor agonist landscape in 2026 spans four distinct compounds: semaglutide (selective GLP-1 RA, MW 4113.58 Da, injectable and oral), tirzepatide (dual GLP-1/GIP agonist, MW 4813.45 Da), retatrutide (triple GLP-1/GIP/glucagon agonist, MW ~4500 Da, Phase 3), and orforglipron (non-peptide oral GLP-1 agonist, MW 541.65 Da, FDA-approved April 2026)
