lcysteine

L-Cysteine (L-(+)-Cysteine) is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, L-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 (L-Cysteine HCl) is a conditionally essential amino acid,L-Cysteine hydrochloride suppresses ghrelin and reduces appetite in rodents and humans

L-Cysteine methyl ester hydrochloride (L-Cysteine methyl ester hydrochloride (Acdrile)) is an antitussive and an expectorant agent, used to relieve breathing difficulties caused by mucus.

L-Cysteine hydrochloride hydrate (L-Cysteine hydrochloride monohydrate) is a conditionally essential amino acid, which acts as a precursor for biologically active molecules such as hydrogen sulphide (H2S), taurine and glutathione. L-Cysteine hydrochloride hydrate suppresses ghrelin and reduces appetite in rodents and humans.

S-(3-Carboxypropyl)-L-cysteine is a thioether derivative of L-cysteine.

Acetylcysteine (NAC) is an N-acetyl derivative of cysteine, a ROS inhibitor and mucolytic agent. Acetylcysteine induces apoptosis, can be used to reduce mucus thickness, and has anti-influenza viral activity.

N-Acetylcysteine amide is a thiol antioxidant and a neuroprotective agent with cell permeability and blood-brain barrier permeability. N-Acetylcysteine amide reduces ROS production.

Gamma-glutamylcysteine TFA (γ-glutamylcysteine TFA) is a precursor of glutathione (GSH) with antioxidant and anti-inflammatory properties. It alleviates oxidative stress and mitochondrial damage induced by ethanol in hepatocytes by increasing cellular GSH, SOD activity, and mitochondrial membrane potential, protecting cells from alcohol-induced liver disease (ALD) by inhibiting oxidative stress, reducing inflammation, and preventing cell apoptosis.

S-Nitroso-N-acetylcysteine inhibits proliferation and survival of multiple MM cells. It acts by the S-nitrosylation-dependent inhibition of STAT3 and NF-κB.

Folcysteine is a cysteine derivative with potential antitumor agent. It's a vitamin that used to synthesize DNA, conduct DNA repair and methylate DNA. It also acts as a cofactor in biological reactions involving folate.

Aminopropylcysteine is a amino acid standard.

Cysteinylcysteine is a bioactive chemical.

Isoleucylcysteine is the first intermediate peptide in bacitracin biosynthesis.

Lysylcysteine is a dipeptide composed of lysine and cysteine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived

N-Acetylcysteine lysinate is a bioactive chemical.

Pantothenoylcysteine is a bioactive chemical.

S-Bimanylcysteine is a bioactive chemical.

Gamma-Glutamylcysteine is a natural dipeptide containing cysteine and glutamic acid, serving as a precursor to glutathione (GSH) and a cofactor for glutathione peroxidase (GPx). Gamma-Glutamylcysteine exhibits anti-inflammatory effects by upregulating IL-10 whilst downregulating TNF-α, IL-6, and IL-1β.

N-Acetyl lysyltyrosylcysteine amide is a non-toxic, potent, reversible, and specific myeloperoxidase (MPO) tripeptide inhibitor that effectively inhibits MPO production in vivo, attenuates neuronal damage, preserves brain tissue and neurological function post-stroke, and inhibits MPO-dependent hypochlorite (HOCl) production, protein nitration, and LDL oxidation. It is also used in the study of bronchial dysplasia.

N-Acetyl lysyltyrosylcysteine amide acetate is an effective and selective tripeptide inhibitor of myeloperoxidase (MPO). N-Acetyl lysyltyrosylcysteine amide acetate inhibits MPO-dependent hypochlorous acid (HOCl) generation, protein nitration, and LDL ox

γ-Glutamyl-S-allylcysteine (L-γ-Glutamyl-(S)-Allyl-Cysteine) is a γ-glutamyl peptide derived from Allium sativum L., known for its anti-glycation and antioxidant properties, as well as its ability to inhibit cholesterol biosynthesis.

Glycylglycylcysteine is an inhibitor of Thrombin Activatable Fibrinolysis Inhibitor (TAFI), exhibiting a K_i value of 0.99 µM and an IC_50 of 9.4 µM in TAFI substrate assays. TAFI, a basic carboxypeptidase, hinders fibrinolysis by cleaving C-terminal lysine residues on partially degraded fibrin [1].

Farnesylcysteine (FC) serves as a competitive inhibitor of ICMT and is associated with an ABA hypersensitive phenotype in Arabidopsis thaliana. The fcly mutant exhibits reduced farnesylcysteine (FC) lyase activity and shows an increased response to ABA [1].

Acetylcysteine-15N is a version of Acetylcysteine (T0875) labeled with nitrogen-15 (\[^15N\]). Acetylcysteine (N-Acetylcysteine) functions as a mucolytic agent, effectively reducing mucus viscosity. As a reactive oxygen species (ROS) inhibitor, it serves as a cysteine precursor and prevents heme-induced ferroptosis by neutralizing toxic lipids produced via arachidonic acid-dependent 5-lipoxygenase activity. Additionally, Acetylcysteine (T0875) can induce apoptosis and exhibits antiviral activity against influenza. It represents the most stable form of cysteine for drug delivery and is utilized in studies of disulfidptosis.
