L-cysteine, also known as cysteine, is a non-essential amino acid in the human body. Amino acids are the constituent units of proteins, and proteins are the material basis of life. From humans to microorganisms, everything is composed of proteins. Proteins are composed of peptides, and the peptide chains of peptides are made up of amino acids. Different proteins are composed of peptide chains of amino acids in different sequences and lengths. Genes related to genetics are actually amino acid chains of different sequences. L-cysteine is closely related to cystine. Two molecules of cysteine form one molecule of cystine. Cysteine is relatively unstable and can easily be converted into cystine. Cystine can also be further reduced to cysteine. Both of these are sulfur-containing amino acids and play a role in the formation and detoxification of the skin. L-cysteine exists in keratin, which is the main protein that constitutes nails, toenails, skin and hair. L-cysteine can help produce collagen tissue and maintain the elasticity and texture of the skin. It is also related to the proteins of digestive enzymes. Cysteine can supply the -SH group to many important enzymes in the body, such as succinate dehydrogenase, lactate dehydrogenase, etc. L-cysteine is mainly applied in the fields of cosmetics, medicine and food. In the field of cosmetics, it is used to prepare hair perming powder, sunscreen, hair growth perfume and hair tonic, etc. It is used in the medical field to prepare drugs such as methylcysteine, ethylcysteine, acetylcysteine, methyl cysteine, ethyl cysteine and comprehensive amino acid preparations. Cysteine can be used as a protective drug against radiation damage. In the field of food, L-cysteine is used as a bread fermentation aid (ripening agent), a stabilizer for antioxidants in milk powder and fruit juice, and a nutrient for pet and livestock food, etc.
