Myocyte Metabolism

Meaning

The integrated biochemical processes occurring within a myocyte, or muscle cell, that govern energy production, substrate utilization, protein turnover, and cellular signaling in response to mechanical and hormonal stimuli. This includes the pathways for glucose uptake, fatty acid oxidation, and the precise balance between protein synthesis and degradation, which ultimately determines muscle mass and functional capacity. Understanding myocyte metabolism is central to optimizing lean body mass, improving insulin sensitivity, and mitigating age-related sarcopenia.
