L-Cysteine Sulfur-Containing Amino Acid

Detailed Description L-Cysteine appears as a white to slightly off-white crystalline powder with a characteristic sulfur odor. It has moderate solubility in water and exhibits strong reducing and antioxidant properties due to the presence of a thiol (–SH) group. L-Cysteine is typically produced through fermentation or hydrolysis processes, followed by purification to ensure high optical purity and low impurity levels. Key quality parameters include assay, optical rotation, moisture content, heavy metals, and microbiological specifications. These indicators are critical for performance in food, pharmaceutical, and cosmetic applications.     Key Characteristics Sulfur-containing amino acid with reducing properties High biological activity and optical purity Functional antioxidant and processing aid Suitable for food, pharmaceutical, and industrial grades Consistent quality and stable performance   Applications Food ProcessingUsed as a dough conditioner and processing aid…
