Fatty acids are a group of carboxylic acids consisting of long aliphatic chains, which can be either saturated or unsaturated. They are typically derived from natural fats and oils through hydrolysis or saponification and appear as colorless to pale yellow liquids or solids depending on the chain length and degree of saturation. Fatty acids are fundamental building blocks in biochemistry and industrial chemistry, serving as raw materials in the manufacture of soaps, detergents, lubricants, cosmetics, plastics, and food additives. Their amphiphilic nature—containing both hydrophilic (carboxyl group) and hydrophobic (alkyl chain) components—makes them versatile for various chemical and industrial applications.
