Gebruike / Function

• "It occurs in sour milk from fermentation of lactose, and it is formed in muscles during the anaerobic cell respirationthat occurs during strenuous exercise. It is also formed during anaerobic muscle activity when glucose cannot be changed to pyruvic acid in glycolysis. It contributes to muscle fatigue. Lactic acid milk (buttermilk or acidophilus milk) helps to prevent the growth of putrefactive bacteria in the large intestine." 1
