L-Cysteine, N-methyl-, hydrochloride (1:1)

Description:

L-Cysteine, N-methyl-, hydrochloride (1:1), with the CAS number 14344-46-8, is a derivative of the amino acid cysteine, characterized by the presence of a methyl group attached to the nitrogen atom of the amino group. This compound typically appears as a white to off-white crystalline powder and is soluble in water, which facilitates its use in various biochemical applications. As a hydrochloride salt, it exhibits enhanced stability and solubility compared to its free base form. L-Cysteine is known for its role as a precursor to the antioxidant glutathione and is involved in protein synthesis, cellular metabolism, and detoxification processes. The N-methylation can influence its biological activity and pharmacokinetics, making it of interest in pharmaceutical and nutritional contexts. Additionally, it may be utilized in research settings for studying protein structure and function, as well as in formulations aimed at enhancing skin health and promoting hair growth. Safety data should be consulted for handling and usage, as with any chemical substance.

3-Mercapto-2-(methylamino)propanoic acidHydrochloride

CAS: 14344-46-8

3-Mercapto-2-(methylamino)propanoic acidHydrochloride (3MA) is a synthetic antibiotic that binds to the phosphate groups of bacterial cell walls. It is a competitive inhibitor of siderophore production, which is an essential process for bacterial uptake of iron. 3MA has been shown to be effective against cultures of enterocolitica and Micacocidin-resistant strains of E. coli. 3MA has also been shown to have anti-inflammatory properties and may be useful in the treatment of colitis caused by Clostridium difficile or Salmonella enterica serovar Typhi infections.
