Adipic Acid

Lactic acid is a chemical compound classified as an organic acid. It is a type of carboxylic acid, specifically known as 2-hydroxypropanoic acid. Lactic acid is produced in the body as a byproduct of anaerobic metabolism, primarily in muscle tissues, during periods of intense physical activity or when oxygen supply is limited. It plays a crucial role in energy production and can serve as an alternative energy source when glucose availability is reduced. In terms of its chemical structure, lactic acid consists of a three-carbon molecule with a hydroxyl group (-OH) and a carboxyl group (-COOH) attached to the second carbon. It exists in two stereoisomeric forms: L-lactic acid and D-lactic acid. L-lactic acid is the most common and biologically active form found in humans. Lactic acid has several industrial applications, including its use in food production, pharmaceuticals, and cosmetics. It is often utilized as a preservative, flavoring agent, pH regulator, and moisturizer. Lactic acid is also employed in various chemical processes, such as the production of biodegradable plastics and environmentally friendly solvents. Overall, lactic acid is an important compound with diverse biological and industrial significance, contributing to various physiological processes and serving as a versatile chemical building block in numerous applications.

Malic acid is a naturally occurring organic compound with the molecular formula C4H6O5. It is a dicarboxylic acid that is commonly found in fruits, particularly in apples, and is responsible for their sour taste. Malic acid is also used in the food industry as a flavor enhancer, acidity regulator, and preservative. It can also be used in various other applications such as in the production of cosmetics, pharmaceuticals, and as a chelating agent in metal complexation reactions.
