Definition


Aspartate Aminotransferase, or AST, is a member of the transferase enzymes found in muscle tissues, principally of the heart and lungs, but also of the kidneys, the liver and the brain. Aspartate Aminotransferase is also found in the skeleton. It allows the creation of new amino acids. When blood has too high a concentration of AST, a myocardial infarction or a hepatic aflliction may be suspect.
