AICAR

AICAR is not a peptide but a nucleotide analog widely studied as an AMPK activator. AMPK is a central energy-sensing pathway that helps regulate glucose uptake, fatty-acid oxidation, mitochondrial activity, and cellular energy balance. In laboratory research, AICAR is frequently used as a tool compound to model exercise-like metabolic signaling and to investigate how cells respond to low-energy states. It has relevance in studies involving skeletal muscle metabolism, endurance biology, insulin sensitivity, lipid oxidation, and mitochondrial function. Researchers value AICAR because it can help isolate AMPK-driven metabolic effects.
