L-Cysteine is one of the 20 natural amino acids and, besides methionine,the only one which contains sulfur. It is a thiol-containing non-essential amino acid that is oxidized to form Cystine. It is a non-essential sulfur-containing amino acid in humans, related to cystine, Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin.
L-cysteine hydrochloride is used in the baking industry as dough conditioner. Specially, it breaks the disulfide bonds of gluten, which lowers the viscosity of the dough. It is then easier to work with and increases the elasticity of the dough, helping it to rise during baking.
L-cysteine is available through many dietary sources, primarily animal protein. Eggs and dairy products also contain significant levels of l-cysteine. Vegetable sources of l-cysteine include broccoli, Brussels sprouts, garlic, granola, sprouted lentils, oats, onions and peppers. The commercial extraction of l-cysteine typically uses human hair, due to its high concentration of this amino acid. Other commercial sources include hog hair and poultry feathers. L-cysteine may also be synthesized in a process that involves fermentation by a variety of E. coli.
L-cysteine is an important precursor for antioxidants such as glutathione - a product metabolized in the liver. Glutathione is essential for the breakdown of toxins in the body, such as alcohol. L-cysteine is also the precursor for other important antioxidants that help ward off cancer by decreasing the incidence of cell mutation.
Cancer is caused by the replication of genetic mistakes (mutations) that go unnoticed by the cell's recognition system. In healthy cells, mutations are caught and denatured before replication continues.
If mutations are not caught, then the on/off mechanisms that monitor cell formation may be disrupted allowing uncontrolled proliferation of cells into tumors. A healthy cell rich in amino acids such as L-cysteine, has a better chance of sensing and discarding such mutations.
L-cysteine benefits can also include improved heart and circulatory system health. Inflammation plays a key role in heart health. The inflammation response causes a cascade of events to bring fluids, proteins and cells to damaged tissues.
Some of these substances carried in an inflammatory response are sticky and can get stuck on the walls of arteries. The presence of L-cysteine has been found to directly regulate this adhesion of sticky substances to the walls of arteries and therefore has a positive effect on the health of our hearts.

Our Raw Materia Factory
Upstream peptide synthesis
Wuhan Newtop Biotech Co., Ltd production plants are endowed with state-of-the-art equipment for solvent supply, peptide synthesis, purification and isolation of active ingredients and intermediates. All equipment and containment is GMP qualified and cleaning validated. Overlapping capacities and sizes of different equipment trains facilitate a smooth scale-up for increases in demand within the product life cycle.
Downstream purification and isolation of peptides
Wuhan Newtop Biotech Co., Ltd is committed to the systematic expansion and modernization of its purification equipment in order to ensure the efficient production of ever-increasing amounts of bulk peptide pharmaceuticals.It uses sophisticated methods for large scale purification campaigns such as preparative high performance liquid chromatography (HPLC), ion exchange (IEX), size-exclusion chromatography (SEC), and ultra-filtration (UF/TFF). The equipment in place permits highly efficient or even continuous manufacturing of extremely pure products up to multi-kg quantities per lot.For preparative HPLC, dynamic axial compression (DAC) stainless steel columns of up to 60 cm diameter both in batch and continuous mode are packed with the appropriate high performance silica separation phase. For low-pressure chromatography columns up to 80 cm diameter are available. Solvent delivery is ensured from eluent tank farms and containers.The control of microbiological contamination is a prerequisite for API manufacturing. Class D (ISO 8) and C (ISO 7) clean rooms are supplied via HEPA-filtered, temperature and humidity controlled air, down-flow booths are used for minimizing microbial contamination and protecting operators. Highly active pharmaceutical ingredients are handled in integrated safety workbenches or flexible isolators reaching OEB level 4 (1-10 µg/m3).Predefined physicochemical properties of the API can only be achieved by a carefully controlled isolation process. Besides precipitation and crystallization, lyophilization of intermediates and final API is a standard unit operation.
Our R&D Laboratories
Wuhan Newtop Biotech Co., Ltd acquired early mastery of development and manufacturing of peptides, the short chain amino acids linked by peptide bonds that have enabled new generations of small molecule drugs that closely mimic the body's natural pathways.Wuhan Newtop Biotech Co., Ltd possesses first-class capabilities to manufacture peptides at industrial scale and in full compliance with the strictest Good Manufacturing Practice (GMP) standards.
