blood chemistry measurement blood enzyme activity level blood aspartate aminotransferase activity level 2011-11-02T04:17:35Z CMO:0000580 EFO:0004736 EFO:0008031 The amount of enzymatic activity of glutamic-oxaloacetic transaminase enzyme, commonly known as aspartate transaminase or aspartate aminotransferase (AST), in a specified sample of blood. AST catalyzes the reversible transfer of an amine group from l-glutamic acid to oxaloacetic acid, forming alpha-ketoglutaric acid and l-aspartic acid. Blood AST level is used as an enzymatic marker for liver disease or damage.
