Malic dehydrogenase, an enzyme crucial for energy production in cells, also goes by several synonymous names. One common synonym is malate dehydrogenase, referring to its function in catalyzing the conversion between malate and oxaloacetate during cellular respiration. Another synonym is oxaloacetate malate dehydrogenase, emphasizing its role in the interconversion of these two important molecules. In a similar vein, it is also known as oxaloacetate-malate shuttle, highlighting its involvement in shuttling electrons during the citric acid cycle. Lastly, it is sometimes referred to as NAD-dependent malate dehydrogenase, emphasizing its reliance on the coenzyme NAD+ for its catalytic activity. Despite the variations, all these terms describe the same vital enzyme in cellular metabolism.
