L-Cysteine hydrochloride anhydrous is a conditionally essential amino acid and a precursor to bioactive molecules such as hydrogen sulfide (H2S), glutathione and taurine. L-Cysteine hydrochloride inhibits ghrelin and reduces appetite in rodents and humans. L-Cysteine Hydrochloride Anhydrous usually appears as colorless to white crystals or crystalline powder with a slight sour taste. It has a higher melting point, good solubility in water, and the aqueous solution is acidic. In addition, it is soluble in alcohol, ammonia and acetic acid, but insoluble in organic solvents such as ether, acetone, and benzene.

5. Product use:
In the field of medicine,
L-Cysteine Hydrochloride Anhydrous plays an important role. It can be used to treat radioactive drug poisoning, heavy metal poisoning, hepatitis and other diseases, and its effect on restoring liver function is remarkable. In addition, it can also be used as an expectorant, which has good effects on improving breathing conditions and treating respiratory diseases such as bronchitis and bronchial asthma. At the same time, L-cysteine hydrochloride anhydrous also has anti-inflammatory, analgesic, and inhibitory effects on the growth of bacteria and cancer cells, so it has broad application prospects in the medical field.
In the field of cosmetics,
L-Cysteine Hydrochloride Anhydrous is favored for its antioxidant, anti-aging, and whitening effects. It can remove free radicals in the body, prevent cell oxidation and aging, promote the synthesis and secretion of collagen, increase skin elasticity and firmness, and reduce the appearance of wrinkles and fine lines. At the same time, it can also inhibit the synthesis and precipitation of melanin and reduce skin spots and dullness, so it is often added to cosmetics such as antioxidant essences, face creams, eye creams, and whitening masks.
In the chemical industry,
L-cysteine hydrochloride anhydrous can be used as a food additive to prevent oxidation and discoloration of vitamin C and maintain the nutritional value and taste of food. In addition, it can also be used in bread making to promote the formation of gluten protein, fermentation, mold release and other processes, and improve the quality and taste of bread.
In the field of feed,
L-cysteine hydrochloride anhydrous can improve coat, promote pigment deposition, promote muscle protein deposition, and increase protein deposition rate. It can also indirectly increase growth hormone levels by depleting growth-inhibiting hormones, thereby increasing the animal's growth rate. In addition, it can enhance the immunity of animals, protect cell membranes, improve the intrinsic quality of muscles, and reduce feeding costs.
As for its application in agriculture, there are currently relatively few specific application cases and studies on L-cysteine hydrochloride anhydrous in agriculture. However, considering its metabolism and functions in organisms, there may be more research and application potential in agricultural fields such as plant protection and soil improvement in the future.
