give short note on myoglobin.
Myoglobin is ahemoprotein which has the ability to bind molecular oxygen. Itoccurs as a monomeric protein in which the globin is surrounding a heme. It acts as a secondary carrier of oxygen in the muscle tissue. When the muscle cells are in action, they need a large amount of oxygen. Muscle cells use these proteinsto accelerate oxygen diffusion and take oxygen for times of intense respiration. The tertiary structure of myoglobin is similar to a typical water soluble globule protein structure.
