Acetaldehyde dehydrogenase
open-in-new
<p>Acetaldehyde dehydrogenases (<a href="/facts/Enzyme_Commission_number/Y5GNLRKX">EC</a> <a href="https://enzyme.expasy.org/EC/1.2.1.10">1.2.1.10</a>) are <a href="/facts/Dehydrogenase/hX7eulAz">dehydrogenase</a> <a href="/facts/Enzyme/DSI1Fh7y">enzymes</a> which catalyze the conversion of <a href="/facts/Acetaldehyde/QllLbSUe">acetaldehyde</a> into <a href="/facts/Acetyl-CoA/XyxFfC84">acetyl-CoA</a>. This can be summarized as follows: </p><p>Acetaldehyde + NAD+ + <a href="/facts/Coenzyme_A/loAfeGpx">Coenzyme A</a> ↔ <a href="/facts/Acetyl-CoA/XyxFfC84">Acetyl-CoA</a> + <a href="/facts/NADH/BHdLW925">NADH</a> + H+ </p><p>In humans, there are three known genes which encode this enzymatic activity, <i><a href="/facts/ALDH1A1/5BwpqEuI">ALDH1A1</a></i>, <i><a href="/facts/ALDH2/nC0H4RfY">ALDH2</a></i>, and the more recently discovered <i><a href="/facts/ALDH1B1/DQj8FoDl">ALDH1B1</a></i> (also known as <i><a href="/facts/ALDH5/DQj8FoDl">ALDH5</a></i>). These enzymes are members of the larger class of <a href="/facts/Aldehyde_dehydrogenase/qNWTxjtR">aldehyde dehydrogenases</a>. </p><p>The <a href="/facts/CAS_number/zjXjCGPx">CAS number</a> for this type of the enzyme is [9028-91-5]. </p>
