Thyroid peroxidase enzyme
Webb30 juli 2024 · Thyroid peroxidase, also called thyroperoxidase (TPO, EC 1.11.1.1-14) or iodide peroxidase, is an enzyme participating in the synthesis of thyroid hormones. In the human body, it is encoded by the TPO gene located on chromosome 2p25 [ 1 ]. WebbPeroxidase is an enzyme found in a wide variety of organisms, from plants to humans to bacteria. Its function is to break down hydrogen peroxide (H2O2), which is one of the toxins produced as a byproduct of using oxygen for respiration. (The fact that it’s toxic is what makes hydrogen peroxide useful in first aid kits.
