L-Cysteine, methyl ester

Description:

L-Cysteine, methyl ester is a derivative of the amino acid L-cysteine, characterized by the presence of a methyl ester group attached to its carboxylic acid functional group. This compound is typically represented by the molecular formula C4H9NO2S. It is a white to off-white crystalline powder that is soluble in water and polar organic solvents, making it useful in various biochemical applications. L-Cysteine, methyl ester retains the thiol (-SH) group characteristic of cysteine, which contributes to its reactivity and ability to participate in redox reactions. It is often utilized in peptide synthesis and as a building block in the production of pharmaceuticals and nutraceuticals. Additionally, it may serve as a reducing agent and antioxidant in biological systems. Due to its role in protein structure and function, L-cysteine derivatives are of interest in studies related to cellular metabolism and oxidative stress. Safety data should be consulted for handling and usage, as with any chemical substance.
