The Different Body Parts Insulin Stimulates

4. Protein Metabolism

Insulin is well known for its role in carbohydrate synthesis, but it is also needed to metabolize protein and transport amino acids. Insulin increases the rate of amino acids to some tissues, especially those that have been injured. It also enhances protein synthesis in the liver, muscle, and adipose tissues, as well as in other tissues throughout the body. Insulin prevents proteins from being broken down in muscle and maybe even in tissue, which helps stabilize muscle strength and ensures the body uses carbohydrates instead of protein for energy.
