N-Acetyl-d3-L-cysteine

Description:
N-Acetyl-d3-L-cysteine is a stable isotopic form of N-acetyl-L-cysteine (NAC), where the hydrogen atoms in the cysteine moiety are replaced with deuterium, a heavier isotope of hydrogen. This compound is characterized by its acetylated thiol structure, which enhances its solubility and bioavailability compared to cysteine. N-Acetyl-d3-L-cysteine is known for its antioxidant properties, acting as a precursor to glutathione, a critical antioxidant in the body. It is often utilized in research settings, particularly in studies involving metabolic pathways and redox biology, due to its isotopic labeling. The compound is typically administered in a powdered form and is soluble in water, making it suitable for various biochemical applications. Its stability and unique isotopic signature allow for tracking and quantifying metabolic processes in vivo. As with other thiol-containing compounds, it may exhibit reactivity with electrophiles, contributing to its biological activity. Overall, N-Acetyl-d3-L-cysteine serves as a valuable tool in both therapeutic and research contexts.
