L-Cysteine, 100 Grams

L-Cysteine is a naturally occurring amino acid that plays a crucial role in the life science marketplace. It is classified as a semi-essential or conditionally essential amino acid because the body can synthesize it to some extent, but certain conditions may necessitate its dietary intake. 

L-Cysteine finds diverse applications due to its unique properties and functions.

Here are some key aspects: 

Antioxidant and Redox Regulation: L-Cysteine is a potent antioxidant and a precursor for the synthesis of glutathione, a major cellular antioxidant. It helps protect cells from oxidative stress and plays a critical role in maintaining redox balance within cells. 

Protein Structure and Function: L-Cysteine contributes to the structure and stability of proteins through the formation of disulfide bonds. These bonds are important for protein folding, stabilization, and proper function. 

Biological Pathways and Metabolism: L-Cysteine is involved in various metabolic pathways, including the synthesis of taurine, coenzyme A, and the polyamines spermine and spermidine. It also participates in the synthesis of other sulfur-containing compounds like cystine, methionine, and glutathione. 

Cell Signaling and Regulation: L-Cysteine plays a role in cell signaling processes, including the regulation of gene expression, cellular proliferation, and apoptosis. It serves as a precursor for the synthesis of hydrogen sulfide (H2S), which acts as a signaling molecule with various physiological functions. 

In the life science marketplace, L-Cysteine is widely used as a supplement in cell culture media and biotechnology processes. It is employed to enhance cell growth, protein production, and overall cell viability. L-Cysteine is also utilized in research studies exploring its potential therapeutic applications, such as antioxidant therapies, neuroprotection, and deto
