<unk>  is a polymorphic enzyme responsible for the oxidation of<unk> ydes to carboxylic acids, which leave the liver and are metabolized by the body’s muscle and heart. There are three different classes of these enzymes in mammals: class 1 (low Km, cytosolic), class 2 (low Km, mitochondrial), and class 3 (high Km, such as those expressed in tumors, stomach, and cornea). In all three classes, constitutive and inducible forms exist.<unk> 1 and<unk> 2 are the most important enzymes for<unk> yde oxidation, and both are tetrameric enzymes composed of 54 kDa subunits. These enzymes are found in many tissues of the body but are at the highest concentration in the liver.
