CAS 56-89-3
:(-)-Cistina
Descripción:
(-)-Cistina, con el número CAS 56-89-3, es un aminoácido que se encuentra de forma natural y juega un papel crucial en la estructura y función de las proteínas. Es una forma dimérica de cisteína, formada por la oxidación de dos moléculas de cisteína, resultando en un enlace disulfuro entre sus grupos tiol. Este compuesto se caracteriza por su apariencia cristalina blanca y es soluble en agua, lo que facilita sus funciones biológicas. (-)-Cistina es esencial para la estabilidad de las estructuras proteicas, particularmente en la formación de estructuras terciarias y cuaternarias debido a su capacidad para formar puentes disulfuro. También está involucrado en varios procesos metabólicos y es importante para la síntesis de glutatión, un antioxidante clave en el cuerpo. En términos de su importancia biológica, (-)-Cistina se encuentra en muchas proteínas y es vital para mantener el equilibrio redox dentro de las células. Su presencia se nota particularmente en la queratina, que es un componente principal del cabello, la piel y las uñas. En general, (-)-Cistina es integral para numerosos procesos fisiológicos y contribuye a la integridad estructural de las proteínas.

CAS:L-Cystine is a nonessential amino acid in humans. It is a sulfur-containing amino acid, which forms the cystine molecule with another L-cysteine molecule. Cystine has been shown to have antioxidant properties due to its redox potentials and ability to form disulfide bonds. L-Cystine can be synthesized by the enzyme ATP-binding cassette transporter using the redox potential of NADH. It also plays an important role in protein synthesis, as it is a component of many proteins, including those that are involved in neural death and bowel disease. L-Cystine has also been found to have physiological effects on the human body at levels that are not toxic.Fórmula:C6H12N2O4S2Pureza:Min 98.5%Forma y color:White PowderPeso molecular:240.3 g/mol(H-Cys-OH)2
