31. Myoglobin , a compound related to hemoglobin, acts to store oxygen in muscle cells.32. Myoglobin is found in vertebrate muscle cells.33. Unlike many marine mammals, crocodilians have little myoglobin to store oxygen in their muscles. 34. Heme groups are also present in myoglobin to store and diffuse oxygen in muscle cells. 35. Hyraxes have highly charged myoglobin , which has been inferred to reflect an aquatic ancestry. 36. Myoglobin is an oxygen-carrying protein which releases the oxygen more slowly into the body.37. Myoglobin with a neutral pH stays red and is nontoxic to tubule cells in the kidneys.38. His urine was saturated with myoglobin . 39. It has a high affinity for myoglobin , about 60 times greater than that of oxygen. 40. This type of myoglobin was not found in 20'control'coprolites in comparable sites.
