What is aspartate aminotransferase (AST)?

What is Aspartate Aminotransferase (AST)? Aspartate aminotransferase is an enzyme involved in the balance of proteins (amino acids). Levels of this molecule in the body can be used as a sign of liver disease and other health problems.

Is aspartate aminotransferase a biomarker for liver injury?

Aspartate aminotransferase (AST), which functions to transaminate aspartate, has been commonly used as a biomarker for hepatic injury. AST is considered a less specific marker for liver injury than ALT, due to expression from other tissues, such as brain, myocardial cells and skeletal muscle cells (Yang, 2014).

What does aspartate transaminase catalyze?

Aspartate transaminase catalyzes the interconversion of aspartate and α-ketoglutarate to oxaloacetate and glutamate . L-Aspartate (Asp) + α-ketoglutarate ↔ oxaloacetate + L-glutamate (Glu)

What chemical reaction does aspartate aminotransferase accelerate?

At a micro level, the direct chemical reaction that aspartate aminotransferase accelerates is the conversion of an amino acid (aspartate) and acid (alpha-ketoglutarate) to a different acid ( oxaloacetate) and amino acid (glutamate).

What is an aspartate aminotransferase (AST) test?

What Is an Aspartate Aminotransferase (AST) Test? The aspartate aminotransferase (AST) test is a blood test that checks for liver damage. Your doctor might order this test to find out if you have liver disease and to monitor your treatment. Your liver is an organ that has many important jobs.

What is aspartate aminotransferase used for?

Aspartate aminotransferase is an enzyme involved in the balance of proteins (amino acids). Levels of this molecule in the body can be used as a sign of liver disease and other health problems. People go to their doctor to get their AST tested as part of a standard panel.

What is AST and what is it for?

What is AST? AST stands for aspartate aminotransferase which is one of the two enzymes produced by the liver. AST also is known as an SGOT or serum glutamic-oxaloacetic transaminase and the protein is found mostly in the liver and other parts of the body like muscles, heart, brain, and kidneys. When our liver gets damaged or ...

What is AST and Alt in the liver?

Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) are enzymes that indicate liver damage or disease at high concentrations in the blood. Sjouke et al. collected data from two studies investigating the effect of various doses of levothyroxine and eprotirome on the liver, respectively.

What is aspartate transaminase?

Aspartate transaminase (AST) is an enzyme that is released when your liver or muscles are damaged. Although AST is found mainly in your liver and heart, AST can also be found in small amounts in other muscles.

What is the function of aspartate aminotransferase?

Aspartate aminotransferase (AST: EC 2.6.1.1) (formerly glutamic oxaloacetic transaminase; GOT) catalyzes the transamination of L-aspartate and 2-oxoglutatarate to oxaloacetate and glutamate. As with ALT, pyridoxal-5′-phosphate (PP) is required as a cofactor.

What is the difference between aspartate and alanine aminotransferase?

Alanine aminotransferase was previously referred to as serum glutamic-pyruvic transaminase or SGPT whereas Aspartate aminotransferase was known as serum glutamic-oxaloacetic transaminase (SGOT). Alanine transaminase catalyzes the interconversion of alanine and alpha-ketoglutarate to glutamate and pyruvate.

What is an aspartate aminotransferase (AST) test?

What Is an Aspartate Aminotransferase (AST) Test? The aspartate aminotransferase (AST) test is a blood test that checks for liver damage. Your doctor might order this test to find out if you have liver disease and to monitor your treatment. Your liver is an organ that has many important jobs.
