BIOCHM-ERQFM8

Lactate dehydrogenase is an enzyme that catalyzes the reaction shown.

$$\text{pyruvate} \space +\space \text{NADH} \space \xrightarrow [ ]{ } \text{ lactate} \space +\space NAD^+$$

In this reaction, the ketone functional group of pyruvate is converted to the alcohol functional group of lactate.

Based on the type of reaction that it catalyzes, lactate dehydrogenase is

enzyme. In the reaction, the pyruvate is

while the NADH is

.

$NAD^+$ is the active co- factor for this enzyme and it is made from the vitamin known as
