These related but non-identical forms are called isoenzymes, or isozymes. Although each isoenzyme carries out the same chemical conversion, the different forms can vary in details such as their exact amino-acid composition, their optimum conditions, or the particular tissue of the body in which they are most abundantly produced, since different tissues may preferentially express different isoenzyme forms of what is, functionally, one enzyme. Lactate dehydrogenase, which occurs as several distinct isoenzyme forms distributed differently …
