hexokinase /hexo·ki·nase/ (hek″so-ki´nās) an enzyme that catalyzes the transfer of a high-energy phosphate group to a hexose, the initial step in the cellular utilization of free hexoses. The enzyme occurs in all tissues as various isozymes with varying specificities; the liver isozyme (type IV) is specific for glucose and is often called glucokinase.
