What are liver enzymes?

Liver enzymes are proteins produced by cells in the liver that play an important role in various biochemical reactions necessary for the proper functioning of the body. These enzymes are involved in breaking down substances, including drugs and toxins, processing and storing nutrients, and producing energy. Common liver enzymes include alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT), among others. Measuring the levels of these enzymes in the blood can help healthcare professionals diagnose liver diseases and monitor the progression of the disease over time.
