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 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.

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.

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.

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.

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.

Penicillamine (Artamine), possessing antineoplastic properties, induces apoptosis by a p53-mediated mechanism and inhibits angiogenesis by chelating with copper, a cofactor for angiogenesis. Artamine is a beta dimethyl analog of the amino acid cysteine. As a degradation product of penicillin antibiotics, Artamine chelates with heavy metals and increases their urinary excretion.

S-allyl-L-cysteine (S-Allylcysteine), a natural constituent of fresh garlic, has antioxidant and anticancer properties in animals.

L-Cysteine S-sulfate (S-Sulfo-L-cysteine) is an effective N-methyl-d-aspartate (NMDA) glutamatergic receptors agonist. L-Cysteine S-sulfate is the substrate for cystine lyase [1].

S-Methyl-L-cysteine (S-Methylcysteine) is a natural product serving as a substrate in the methionine sulfoxide reductase A (MSRA) catalyzed antioxidant system, exhibiting neuroprotective, antioxidative, and anti-obesity properties.

L-Cysteinesulfinic acid is an endogenous neurotransmitter with agonistic effects on a variety of metabotropic glutamate receptors (mGluRs), including mGluR1, mGluR5, mGluR2, mGluR4, mGluR6, and mGluR8, with a pEC50 = 2.7 to 4.0. L- Cysteinesulfinic acid is a pld-coupled agonist of metabotropic excitatory amino acid (EAA) receptors.

D/L-Cysteine is a useful organic compound for research related to life sciences. The catalog number is T125019 and the CAS number is 3374-22-9.

S-1-Propenyl-L-cysteine, a stereoisomer of S-allyl-l-cysteine, exhibits immunomodulatory effects and has been shown to decrease blood pressure in hypertensive animal models.

γ-Glutamyl-S-1-propenyl cysteine is a compound obtained from garlic with strong free radical scavenging activity.

S-Allylmercapturic Acid (N-Acetyl-S-allyl-L-cysteine) is a metabolite of S-allyl-L-cysteine present in black garlic with potential anti-gout effects, inhibiting both CYP2D6 and CYP-catalyzed reactions.

γ-L-Glutamyl-S-allyl-L-cysteine is an organosulfur compound naturally present in garlic [1].

(R)-1-PeCSO, also known as trans-(+)-S-1-Propenyl-L-cysteine sulfoxide, constitutes the primary flavor precursor in onions [1].

DL-Cysteine (Standard) is a reference standard for DL-Cysteine, suitable for quantitative analysis, quality control, and biochemical experiments.At high concentration, DL-Cysteine acts as an agonist for NMDA/quisqualate receptors and is commonly used in exploring neurobiological mechanisms.

L-Cysteine (Standard) is the standard substance of L-Cysteine, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. 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.
