Sodium Pyruvate Sodium pyruvate is added to many media formulations as a carbohydrate source that cells can easily access for energy production. It is also involved in amino acid metabolism and aerobic respiration. Molecular Structure Pyruvate is an anion of pyruvic acid and the end product of glycolysis. The glycolytic pathway, which occurs in the cytosol of aerobic organisms, converts glucose to pyruvate, which then undergoes oxidative decarboxylation in mitochondria to form acetyl CoA, the metabolite that initiates the Kreb’s Cycle.¹ Some microorganisms convert pyruvate to ethanol through the energy-producing process of alcoholic fermentation when under anaerobic conditions.² Prior to it’s conversion to acetyl CoA, pyruvate may also be used to produce alanine by transamination. In the synthesis of alanine, pyruvate is the amino-group acceptor.1 Our Sodium Pyruvate solution is offered as a 100 mM sterile solution in cell culture grade distilled, deionized water. A dilution of 1:100 to yield a 1mM (110 mg/L) working concentration is suitable for most cells. References 1. Moran, L.A., and Scrimgeour, K.G. Biochemistry. 2nd Ed.

Pyruvate also takes on antioxidant duties in low oxygen environments.
