N-Palmitoyl Glutamine: A Novel Molecular Link Between Exercise, Mitochondrial Efficiency, and Human Longevity
By MedXY|Dec 25, 2025
A groundbreaking study identifies N-palmitoyl glutamine (NPG) as a key molecular transducer of cardiorespiratory fitness. NPG correlates with VO2max, increases with exercise training, predicts lower mortality, and directly enhances mitochon
