Lactic acid is an organic compound whose IUPAC name is 2-Hydroxypropanoic acid. Its chemical formula is CH3CH(OH)CO2H, and its CAS number is 50-21-5. It is made up of three carbon — C — atoms, six hydrogen — H — atoms, and three oxygen — O —atoms. The compound has two states — solid and liquid. When solid, it is white and can be dissolved in water. The liquid form is colorless. It is classified as an alpha-hydroxy acid — or AHA. Its conjugate base is lactate, which is critical to a number of biochemical processes.

Synthetic lactic acid production utilizes bacteria to derive lactic acid from simple carbohydrates such as galactose, sucrose, or glucose. It is similar to the process of acid production in the human mouth that leads to tooth decay. The compound can also be manufactured from acetaldehyde, a component of crude oil and coal.

Quick Answers

Lactic acid can be produced naturally by animals, as well as by means of a synthetic process. In animals — including humans — lactate is produced as a result of a fermentation process that occurs both during a creature’s normal metabolism and during exercise. When more lactic acid is produced than is removed, it increases in concentration and causes a burning sensation.
