<prompt> The heme prosthetic group is found inMyoglobinCytochrome oxidaseXanthine oxidaseTyrosine  <response>: Myoglobin is a monomeric protein that acts as a secondary oxygen transporter and binder in the muscle tissues. Furthermore, the tertiary feature of myoglobin resembles water-soluble globule protein characteristics. The diffusion and use of oxygen in the muscles are necessary for the bodily system processes such as respiration.Myoglobin has 8 right-handed a-helices separately forming a polypeptide chain and each contains a single heme prosthetic group with a central bound iron atom.
