CAS 52-90-4: L-(+)-Cisteína
Descripción:
L-(+)-Cisteína, con el número CAS 52-90-4, es un aminoácido que se encuentra de forma natural y que desempeña un papel crucial en la síntesis de proteínas y en varios procesos metabólicos. Se clasifica como un aminoácido no esencial, lo que significa que el cuerpo puede sintetizarlo a partir de otros compuestos. La cisteína contiene un grupo tiol (-SH), lo que la convierte en un aminoácido que contiene azufre, contribuyendo a sus propiedades únicas, como la capacidad de formar enlaces disulfuro que estabilizan las estructuras proteicas. Este aminoácido es conocido por sus propiedades antioxidantes, ya que puede ayudar en la síntesis de glutatión, un antioxidante vital en el cuerpo. L-(+)-Cisteína se encuentra típicamente en alimentos ricos en proteínas y también está disponible como suplemento dietético. Es soluble en agua y tiene una naturaleza ligeramente ácida, con un valor de pKa que refleja su capacidad para donar protones. Además de su importancia biológica, la cisteína se utiliza en diversas aplicaciones industriales, incluida la producción de productos farmacéuticos y cosméticos, debido a sus propiedades funcionales.

CAS:L-Cysteine is a non-essential amino acid that is used in biochemical research and has been shown to inhibit the activity of nicotinic acetylcholine receptors. It also regulates the response of cells to toll-like receptor ligands by inhibiting the production of inflammatory mediators. L-Cysteine binds to a sequence called response element, which is found in many prokaryotic genes, and inhibits protein oxidation. L-Cysteine has an inhibitory effect on single-stranded RNA and can act as a rate constant for protein synthesis. L-Cysteine is an amino acid that contains sulfur and can be found in proteins with thiol groups. The cysteine residues in proteins are coordinated geometrically by a zinc ion (Zn2+) or iron ion (Fe3+). This coordination geometry affects the biological properties of these proteins.Fórmula:C3H7NO2SForma y color:White PowderPeso molecular:121.16 g/molL-Cysteine

CAS:L-Cysteine is used as a precursor in food, pharmaceutical and personal care products. It is actively involved in the production of flavors such as meat flavor obtained by reacting with sugars. Also used for the cleavage of disulfide bonds in the hair's keratin. It plays an important role as a key raw material for the manufacture of N-acetyl-L-cysteine, S-carboxymethyl-L-cysteine and L-cysteine base. Its derivative, N-acetyl-L-cysteine is used as a dietary supplement. It acts as an antidote to acetaminophen overdose and prevents liver failure. It protects nerves from oxidation and thereby prevents illnesses like Alzheimer's and Parkinson's. Being an essential amino acid, it used as animal feed especially for sheep, which is responsible the growth of wool.

CAS:L-Cysteine is a non-animal derived amino acid that has been shown to help maintain normal iron levels in the body. It also helps reduce oxidative injury and inflammation. L-Cysteine is made naturally by the human body, but can be found in some foods as well. L-Cysteine has been shown to help regulate protein oxidation and injury responses in humans. L-Cysteine plays a role in the immune system by binding to Toll-like receptors, which are proteins on cells that are involved with inflammation and immunity. L-Cysteine also plays a role in the immune system by stimulating antibody production, which is important for fighting infection. Cysteine is an amino acid involved with many biochemical reactions, including synthesis of proteins and DNA molecules. Cysteine also regulates gene expression through response elements that are found in the promoter regions of genes. The rate constant for cysteine is 0.00001s^(-1).Fórmula:C3H7NO2SForma y color:White PowderPeso molecular:121.16 g/molL-Cysteine
