lactic acid


lactic acid
a compound that forms in the cells as the end-product of glucose metabolism in the absence of oxygen (see glycolysis). During strenuous exercise pyruvic acid is reduced to lactic acid, which may accumulate in the muscles and cause cramp. Lactic acid (owing to its low pH) is an important food preservative. The lactic acid produced by the fermentation of milk is responsible for the preservation and flavour of cheese, yoghurt, and other fermented milk products.
