Alanine aminotransferase (ALT) is an enzyme that plays a pivotal role in the body’s metabolic processes, particularly in the liver. As a biomarker for liver health, understanding ALT is essential for both medical professionals and patients alike. Abnormal levels of this enzyme can provide critical insights into liver function and potential underlying health issues. This article aims to elucidate the importance of alanine aminotransferase in hepatic function and the implications of its levels on overall liver health.
The Critical Role of Alanine Aminotransferase in Hepatic Function
Alanine aminotransferase is an enzyme primarily found in the liver, where it facilitates the conversion of alanine and α-ketoglutarate into pyruvate and glutamate. This transamination reaction is a vital part of amino acid metabolism and gluconeogenesis, linking protein metabolism and energy production. Given this critical function, ALT is not just an ordinary enzyme but a cornerstone of metabolic activity in the liver, contributing to both energy balance and nitrogen metabolism
