The term E.C. denotes the code number for the enzyme. The number 2 denotes the class of the enzymes transferase. The number 7 denotes the subclass which includes the transfer of phosphate group. The number 1 denotes the subsubclass in which the alcohol molecule acts as the acceptor. The last number 1 denotes the hexokinase.
