Aldehyde dehydrogenase is an important enzyme in the body that helps convert aldehydes into carboxylic acids. This process is crucial for metabolizing various substances, including alcohol and certain drugs. By facilitating this conversion, the enzyme plays a key role in detoxifying harmful compounds and maintaining metabolic balance. This enzyme is found in many tissues, including the liver, where it helps process alcohol. Variations in the ALDH2 gene can affect how individuals metabolize alcohol, leading to differences in tolerance and susceptibility to alcohol-related health issues. Understanding aldehyde dehydrogenase is essential for studying metabolism and related disorders.
