alanine transaminase

 [al´ah-nēn trans-am´ĭ-nās]
an enzyme that catalyzes the reversible transfer of an amino group from alanine to α-ketoglutarate to form pyruvate and glutamate. Normally present in many tissues and body fluids, especially in the liver, it is released into the serum as a result of tissue injury; the serum concentration is increased particularly when there is acute damage to hepatic cells, as in viral or toxic hepatitis, infectious mononucleosis, and obstructive jaundice. Called also alanine aminotransferase and glutamic-pyruvic transaminase.

al·a·nine a·mi·no·trans·fer·ase (ALT),

(al'ă-nēn a-mē'nō-tranz'fer-ās),
An enzyme transferring amino groups from l-alanine to 2-ketoglutarate, or the reverse (from l-glutamate to pyruvate); one d-alanine transaminase effects the same reaction, but using d-alanine and d-glutamate. Serum concentration is increased in viral hepatitis and myocardial infarction.

alanine transaminase

/al·a·nine trans·am·i·nase/ (trans-am´ĭ-nās) an enzyme normally present in serum and body tissues, especially in the liver; it is released into the serum as a result of tissue injury, hence the concentration in the serum may be increased in patients with acute damage to hepatic cells.

al·a·nine a·mi·no·trans·fer·ase

(ALT) (al'ă-nēn ă-mē'nō-trans'fĕr-ās)
An enzyme transferring amino groups from l-alanine to 2-ketoglutarate, or the reverse (from l-glutamate to pyruvate); serum concentration is increased in viral hepatitis and myocardial infarction.
Synonym(s): glutamic-pyruvic transaminase, serum glutamic-pyruvic transaminase.

(ALT) (al'ă-nēn ă-mē'nō-trans'fĕr-ās)
An enzyme transferring amino groups from l-alanine to 2-ketoglutarate, or the reverse (from l-glutamate to pyruvate); serum concentration is increased in viral hepatitis and myocardial infarction.
Synonym(s): glutamic-pyruvic transaminase, serum glutamic-pyruvic transaminase,
alanine transaminase.

Meanwhile, the drug appears to be dose-related acts but on the other hand no significant change in alanine amino transferase (ALT) and malondialdehyde (MDA) in this study were consistent with the expected results [17,15] at least with these doses.
The woman's values were aspartate amino transferase (ASAT) 48 IU/L (normal <26); alanine amino transferase (ALAT) 29 IU/L (normal <27); gamma glutamyl transferase (g-GT) 32 IU/L (normal <200); and lactate dehydrogenase (LDH) 517 IU/L (normal <250).
The serum enzymes namely, acid phosphatase and alkaline phosphatase (ALP) were determined as described by Powell and Smith[15] while the method of Reitman and Frankel[17] was adopted for aspartate aminotransferase (AST) and alanine amino transferase (ALT) using Bausch and Lamb spectrophotometer.
