                                According to a 2023 review, the regulation of amino acid catabolism is now recognized as an important element for metabolic control in various physiological processes, including immune response, obesity, and thermogenesis. This dynamic process has multiple control points, which makes identifying a single, universally applicable rate limiting step of amino acid catabolism challenging, as it depends on the specific amino acid and the body's metabolic state.
