Leucine protects mitochondrial proteins to boost cellular energy production

Science Daily Exercise reported that the essential amino acid leucine boosts cellular energy production by protecting key proteins on mitochondria from being destroyed. Mitochondria produce much of the energy that human cells need to grow, repair tissues, and perform daily functions. [1]

Proteins are essential nutrients that build body tissue and provide energy, according to Wikipedia. Grokipedia notes that leucine regulates protein synthesis in skeletal muscle by activating the mTORC1 signaling pathway, which helps stimulate muscle growth and repair. [2][3]

Grokipedia also notes that leucine supports energy metabolism by promoting glucose uptake, fatty acid oxidation, and mitochondrial biogenesis. It plays a role in insulin sensitivity and helps prevent muscle wasting during aging and exercise recovery. [3]

Science Daily Exercise reported that this new link between nutrition and metabolism could eventually inform new therapeutic approaches for metabolic disorders and cancer. [1]
