Growth in the pharmaceutical sector also fuels demand due to its role in drug formulations, antioxidant properties, and respiratory treatments. Cysteine is a sulfur-containing amino acid with a chemically reactive hydroxyl group, giving it unique properties. It plays a crucial role in protein stability by forming disulfide bridges. This allows for the formation of strong fiber strands, such as those found in hair, wool, and feathers, as well as in horns, hooves, and nails. These structures are composed of proteins with a high cysteine content, with feathers being the primary source of cysteine.

Cysteine can also be extracted from human hair, bristles, and swine hooves. The product for extracting cysteine from feathers involves boiling them in hydrochloric acid. Wacker Chemie AG has developed a method for producing L-cysteine using bacterial fermentation.
