piimhappid

Piimhappid are organic compounds that are central to various biological and industrial processes. Chemically, they are carboxylic acids with the formula C3H6O3, characterized by a hydroxyl group and a carboxyl group on adjacent carbon atoms. The most common form is lactic acid, which exists as two stereoisomers: L-lactic acid and D-lactic acid. L-lactic acid is the predominant form found in biological systems.

In living organisms, piimhappid are produced through glycolysis, a metabolic pathway that breaks down glucose. This anaerobic process is crucial for energy production in muscle cells during intense activity, leading to the buildup of lactic acid. It is also involved in the fermentation processes carried out by certain bacteria, which are responsible for the production of dairy products like yogurt and cheese.

Industrially, piimhappid have numerous applications. They are used as food additives, primarily as acidulants, flavor enhancers, and preservatives. Their antibacterial properties make them useful in the food industry to extend shelf life. Furthermore, piimhappid are employed in the pharmaceutical industry, in cosmetics for their exfoliating properties, and in the production of biodegradable plastics, such as polylactic acid (PLA). The versatility and biological origin of piimhappid contribute to their widespread use.
