isoenzymes

Isoenzymes are different forms of the same enzyme that exist in the body, each slightly different in structure but performing similar functions. They allow the body to fine-tune biological processes in different tissues or conditions. For example, different isoenzymes of lactate dehydrogenase are found in the heart and liver, helping indicate where damage or disease might be occurring. These variations help the body adapt enzyme activity to specific tissue needs, making isoenzymes important in diagnoses and understanding how organs function.
