Its thick fur helps to keep it warm in the cold mountain environment, while its long, bushy tail helps it balance while climbing trees. The hemoglobin molecule is made up of four sub protein molecules in which two chains are alpha globulin chains, and the other two are beta globulin chains. Trypsin digestion of the abnormal hemoglobin resulted in a smaller than normal HPLC peak for the 9 segment of -globin, which is composed of amino acids 67 through 82, and the appearance of a new peak at 193 min.
