Mitochondrial L-2-Hydroxyglutarate Identified as Physiological Signalling Metabolite (nature.com)

• L-2HG identified as a physiological signaling metabolite
• Mitochondrial production influences cellular signaling pathways
• Discovery emphasizes value of metabolomics for functional studies

"Researchers have shown that mitochondrial L-2-hydroxyglutarate (L-2HG) functions as a physiological signaling molecule, not merely a biomarker or byproduct. This finding challenges previous assumptions, indicating L-2HG plays a role in metabolic regulation. The study provides evidence of L-2HG interaction with specific cellular pathways, potentially impacting understanding of metabolism and disease. The discovery underscores the value of metabolomics in uncovering new metabolite functions and has implications for targeted LC-MS methods and biomarker development."
