This table provides a comparison between L-Cysteine Hydrochloride Monohydrate and anhydrous L-Cysteine in terms of molecular weight and CAS number. The IUPAC name is provided for L-Cysteine Hydrochloride Monohydrate, while the anhydrous form does not have a specific IUPAC name listed in the provided data .
L-Cysteine is recognized for its role in the synthesis of proteins and its high reactivity due to the thiol group (-SH), which is essential for many of its biological functions in humans . It is used in the food industry as a flavoring or chelating agent, in pharmaceuticals, and in cosmetics for skin or hair care formulas. The effectiveness and role of L-Cysteine in health and medicine, however, remain subjects of ongoing research and debate .
