2-hydroxy-propanoic acid (CH3.CHOH.CO2H), a syrupy liquid, soluble in water; found in milk, wine and many fruits; used as a food additive and in many industrial applications
Lactic acid is a type of acid which is found in sour milk and is also produced by your muscles when you have been exercising a lot. A syrupy, water-soluble liquid, C, produced in muscles as a result of anaerobic glucose metabolism, and present in sour milk, molasses, various fruits, and wines. A synthetic form of the compound is used in foods and beverages as a flavoring and preservative, in dyeing and textile printing, and in pharmaceuticals. an acid produced by muscles after exercising and found in sour milk. Carboxylic acid found in certain plant juices, in blood and muscle, and in soil. In blood it occurs in the form of its salts (lactates) when glycogen is broken down in muscle; it can be reconverted to glycogen in the liver. Stiffness and soreness after prolonged heavy exercise are due to accumulated lactic acid in the muscles. The end product of bacterial fermentation, lactic acid is the most common acidic constituent of fermented milk products (e.g., sour milk and cream, cheese, buttermilk, yogurt). It is used in other foods as a flavouring or preservative and industrially in tanning leather and dyeing wool and as a raw material or catalyst in many chemical processes
