Liver enzymes are proteins produced by the liver that help facilitate various biochemical reactions in the body. They play a crucial role in processes such as digestion, metabolism, and detoxification. Common liver enzymes include alanine aminotransferase (ALT) and aspartate aminotransferase (AST), which are often measured in blood tests to assess liver health. Elevated levels of liver enzymes can indicate liver damage or disease, such as hepatitis or fatty liver disease. Regular monitoring of these enzymes can help healthcare providers diagnose and manage liver-related conditions effectively, ensuring timely intervention when necessary.
