L-Cysteine, ethyl ester, hydrochloride

Description:

L-Cysteine, ethyl ester, hydrochloride is a derivative of the amino acid cysteine, characterized by the presence of an ethyl ester group and a hydrochloride salt form. This compound is typically a white to off-white crystalline powder, soluble in water, which enhances its bioavailability. As a thiol-containing amino acid, L-cysteine plays a crucial role in protein synthesis and acts as a precursor to the antioxidant glutathione. The ethyl ester modification can improve its absorption and stability compared to its free form. In biological systems, L-cysteine is involved in various metabolic processes, including detoxification and the synthesis of other biomolecules. The hydrochloride form indicates that the compound is in a salt form, which can influence its solubility and stability. L-Cysteine, ethyl ester, hydrochloride is often used in nutritional supplements and research applications, particularly in studies related to oxidative stress and cellular health. As with any chemical substance, proper handling and safety precautions should be observed due to its potential reactivity and biological effects.

L-Cysteine ethyl ester HCl is a disulfide bond that is used in the synthesis of proteins. It is also used to prevent hair loss and to treat baldness. L-Cysteine ethyl ester HCl has potent antitumor activity, which may be due to its ability to react with nucleophilic substitutions. In addition, L-Cysteine ethyl ester HCl can induce apoptosis by binding to the apoptosis protein. The reaction mechanism is not well understood but it may involve hydroxide ion and organometallic complexes. L-Cysteine ethyl ester HCl is soluble in water at neutral pH and poorly soluble in ethanol. It hydrolyzes in the presence of acid or base, forming trifluoroacetic acid or sodium hydroxide solution respectively.
