DL-Cysteine, hydrochloride

Description:
DL-Cysteine hydrochloride is a crystalline compound that serves as a source of the amino acid cysteine, which is a vital building block for proteins. It is a racemic mixture of both the D- and L- forms of cysteine, with the L-form being biologically active and more prevalent in nature. This substance is typically encountered as a white to off-white powder and is soluble in water, making it useful in various biochemical applications. DL-Cysteine hydrochloride is often utilized in cell culture media, as it plays a crucial role in cellular metabolism and antioxidant defense due to its thiol (-SH) group, which can participate in redox reactions. Additionally, it is employed in the synthesis of pharmaceuticals, food additives, and as a reducing agent in various chemical processes. The hydrochloride form enhances its stability and solubility. As with many amino acids, it is important to handle DL-Cysteine hydrochloride with care, as it can be sensitive to oxidation and may have specific storage requirements to maintain its integrity.
