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.

  • L-Cysteine

    CAS:
    <p>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.</p>
