L-Cysteine is a semi-essential amino acid, which means that it can be biosynthesized in humans. The majority of L-cysteine is obtained industrially by hydrolysis of poultry feathers or human hair. Cysteine, mainly the L-enantiomer, is a precursor in the food, pharmaceutical, and personal-care industries. One of the largest applications is the production of flavors. The reaction of cysteine with sugars in a Maillard reaction yields meat flavors, for example. L-Cysteine is also used as a processing aid for baking.
