glutamic-oxaloacetic transaminase

aspartate transaminase

(AST) (ASAT) [ah-spahr´tāt trans-am´ĭ-nās] an enzyme that catalyzes the reversible transfer of an amino group from aspartate to α-ketoglutarate to form glutamate and oxaloacetate, requiring the coenzyme pyridoxal phosphate; it is normally present in serum and in various body tissues, especially in the heart and liver. (See accompanying table.) It is released into the serum as the result of tissue injury, especially injury to the heart or liver, hence the concentration in the serum may be increased in myocardial infarction or acute damage to hepatic cells. Serum levels are also increased in some muscle diseases, such as progressive muscular dystrophy. Called also glutamic-oxaloacetic transaminase.

an enzyme catalyzing the reversible transfer of an amine group from l-glutamate to oxaloacetate, forming α-ketoglutarate and l-aspartate; an aid in diagnosing viral hepatitis and myocardial infarction. Synonym(s): aspartate transaminase, glutamic-aspartic transaminase, glutamic-oxaloacetic transaminase, serum glutamic:oxaloacetic transaminase

(AST) (as-pahr'tāt ă-mē'nō-trans'fĕr-ās) An enzyme catalyzing the reversible transfer of an amine group from l-glutamic acid to oxaloacetic acid, forming α-ketoglutaric acid and l-aspartic acid; a diagnostic aid in viral hepatitis and in myocardial infarction.
