aminotransferases

Enzymes present in liver cells which are released into the blood in liver disease, such as HEPATITIS, that damages liver cells. The most important are aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Measurement of the levels of these enzymes in the blood is a valuable test of liver damage.
