Homework Answers
Propionate Is converted to propionyl- CoA which enters the TCA cycle. However, when there occurs more generation of it, it has drastic effects on the bacterial growth. It is believed that generation of more propionyl-CoA causes inhibition of pyruvate dehydrogenase enzyme. This stops the metabolic generation of energy which is needed by the bacteria for their growth. Thus, bacterial growth is reduced.

Propionate is commonly used as an inhibitor of microbial growth. This growth inhibition comes from propionate being converted into propionyl-CoA (shown below) and then entering the TCA cycle. Explain why this results in growth inhibition.

1. An important paper published by Granchi et al. summarizes therapeutic potential of lactate dehydrogenase inhibitors (Curr Med Chem. 2010;17(7):672-97). Part of the abstract from this paper is shown below: Abstract: "In many different species, lactate dehydrogenase (LDH) constitutes a major checkpoint of anaerobic glycolysis, by catalyzing the reduction of pyruvate into lactate. This enzyme has recently received a great deal of attention since it may constitute a valid therapeutic target for diseases so different as malaria and cancer. In...
