In enzymology, L-lactate dehydrogenase (cytochrome) (EC number 1.1.2.3) is an enzyme that catalyzes the chemical reaction

+ 2 H+
 

The substrate of this enzyme is (S)-lactic acid, which is acted on by two equivalents of the cofactor, ferricytochrome c, which oxidises the hydroxy group to a keto group, giving pyruvic acid, while the cofactor's iron is reduced. [1] [2] [3] [4]
