Final answer:
The abbreviation for Alanine Aminotransferase is ALT, also known as SGPT. It is a key enzyme in amino acid metabolism and liver function monitoring.
Step-by-step explanation:
The abbreviation for Alanine Aminotransferase is ALT, which stands for Alanine transaminase, and it is also known as Serum glutamyl pyruvate transaminase (SGPT). Alanine Aminotransferase (ALT) is an enzyme that plays a crucial role in the metabolism of amino acids. It catalyzes the transfer of an amino group from alanine to alpha-ketoglutarate, forming pyruvate and glutamate. ALT is particularly important in diagnosing liver health, as its levels may increase in the blood due to liver damage such as hepatitis or liver injury. It's used in conjunction with other tests such as Aspartate Aminotransferase (AST or SGOT) and alkaline phosphatase (ALP) to monitor liver function.
