Guanidinopropionic Acid
Guanidinopropionic Acid (GPA) is a significant creatine analogue that competitively inhibits cellular creatine uptake. Its influence on energy metabolism has been extensively studied, revealing effects across skeletal muscle, cardiac tissue, and the brain.
- Impact on Skeletal Muscle: Studies on the effects of GPA on skeletal muscle show a marked decrease in intracellular creatine and phosphocreatine. This leads to a metabolic shift from glycolytic to oxidative pathways, enhancing endurance capacity and improving glucose uptake.
- Cardiac Function Modulation: While the shift to mitochondrial metabolism is less pronounced in heart tissue, GPA can lead to modestly reduced myocardial contractility, affecting ventricular pressure.
- Brain Energy Stability: In brain tissue, adaptations in energy metabolism resulting from GPA intake have been shown to enhance ATP stability and increase survival during hypoxic conditions.
- Research Applications: GPA is a valuable tool for researchers studying cellular energy metabolism, particularly its role in muscle physiology and neurological protection.
