What does isoenzyme mean?
Isoenzymes are multiple forms of an enzyme that differ in their amino acid sequence but have the same function and catalytic activity. They are often used in biochemical research to understand the mechanisms of enzyme function and regulation. Isoenzymes can have different kinetic properties, substrate specificities, and regulatory mechanisms, which can be studied to understand their roles in various metabolic pathways. The study of isoenzymes has important implications for understanding human diseases, such as cancer and diabetes, where enzyme function and regulation are critical. Overall, isoenzymes are a crucial aspect of biochemical research, and their study has led to significant advances in our understanding of enzyme function and regulation.

Etymology of isoenzyme
The term 'isoenzyme' was coined in the 1950s to describe the multiple forms of an enzyme that differ in their amino acid sequence but have the same function and catalytic activity. The prefix 'iso-' comes from the Greek word 'isos', meaning 'equal', and the suffix '-enzyme' comes from the Greek word 'enzyein', meaning 'to work'. The study of isoenzymes has its roots in the work of biochemists such as Fritz Lipmann and Hans Krebs, who first described the concept of isoenzymes in the 1940s and 1950s.
