Lactic Acid

Saturday, October 10, 2015

Lactic acid is a colorless, water-soluble liquid, which is generated in the skeletal muscles as the result of glycolysis, which is in turn the breakdown of glucose into both pyruvic and lactic acid. Thus, it is the byproduct of anaerobic glucose metabolism in the striated muscle, but it is oxydized aerobically in the heart, where lactid acid is converted back into glucose; however, in the skeletal muscles, where this back conversion does not take place, it is accumulated excesively after strenuous physical exercises, provoking cramps. In the nature, lactic acid is also found in sour milk and fruit, being used as preservative; in this case, it is produced by bacteria during fermentation.

Chemical formula: C3 H6 O
