A process called Anaerobic Production of Lactic Acid
The widely-used organic compound lactic acid can be found in many applications, such as flavoring agents and food preservatives. It is mostly produced by an anaerobic process (Vijayaraghavan 2019). The fermentation of microorganisms such as yeast and bacteria produces pyruvate. This 3-carbon molecule is the basis for this organic compound. This enzyme, lactate dehydrogenase, (LDH), converts the pyruvate into lactic acid in absence of oxygen. This is an energy-producing metabolic pathway that is the main energy source for the skeletal muscles when they are engaged in intense exercise (Vijayaraghavan 2019,). It is complex to anaerobic produce lactic acid. The enzyme LDH converts pyruvate into lactate in the initial step. This is followed by the reduction NAD+ to NADH+H+. After the reaction of lactose, the NADH+H+ becomes NAD+.
