Aminotransferase meaning

Aminotransferase definitions

Aminotransferase, also known as transaminase, is an enzyme found in various tissues of the body, including the liver, heart, and muscles. These enzymes play a crucial role in amino acid metabolism, which is essential for protein synthesis and other vital biological processes.

Aminotransferase enzymes catalyze the transfer of amino groups from amino acids to alpha-keto acids, producing other amino acids and alpha-keto acids in the process. This allows for the interconversion of different amino acids, which is necessary for the body to maintain a proper balance of these essential building blocks of proteins.

Types of Aminotransferases

There are several types of aminotransferases, each specific to different amino acids. Some of the most well-known aminotransferases include alanine aminotransferase (ALT), aspartate aminotransferase (AST), and glutamine oxaloacetate aminotransferase (GOT).

ALT and AST

Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are two of the most commonly measured aminotransferases in clinical settings. Elevated levels of these enzymes in the blood may indicate liver damage or other health conditions.

Monitoring aminotransferase levels through blood tests can help healthcare providers diagnose liver diseases, such as hepatitis, cirrhosis, and fatty liver disease. These tests can also be used to monitor the progression of treatment and assess the overall health of the liver.

Overall, aminotransferases are essential enzymes that play a critical role in maintaining the body's amino acid balance and supporting various metabolic functions. Monitoring their levels can provide valuable insights into a person's health and help detect underlying medical conditions.
