2-(Acetilamino)-2-desoxi-3-O-β-D-galactopiranosil-D-galactopiranosa

Descripción:

2-(Acetilamino)-2-desoxi-3-O-β-D-galactopiranosil-D-galactopiranosa, comúnmente referido como un derivado de galactosa, es un carbohidrato con características estructurales notables. Este compuesto consiste en dos unidades de galactopiranosa unidas a través de un enlace glucosídico, con un grupo acetilamino en la posición 2 de uno de los moieties de azúcar. La presencia del grupo acetilamino mejora su solubilidad y reactividad, haciéndolo relevante en diversas aplicaciones bioquímicas. La configuración β-D-galactopiranosil indica que el grupo hidroxilo en el carbono anomérico está en la posición ecuatorial, lo cual es significativo para sus interacciones biológicas. Este compuesto puede exhibir propiedades como ser un sustrato para enzimas específicas o servir como un bloque de construcción en la síntesis de glicoproteínas. Su número CAS, 20972-29-6, permite una identificación precisa en bases de datos químicas. En general, esta sustancia es de interés en campos como la química medicinal y la bioquímica, particularmente en el estudio de la glicosilación y las interacciones carbohidrato-proteína.

Galacto-N-biose

CAS: 20972-29-6

2-Acetamido-2-deoxy-3-O-(b-D-galactopyranosyl)-D-galactopyranose (also known as galacto-N-biose, GNB and T antigen) is a β 1-3’ linked disaccharide which is found in the gastrointestinal tract as a core component of mucin. GNB has been shown to have potential to protect against glutamate excitotoxicity, a process in which nerve cells can be damaged or destroyed. GNB, along with lactose-N-biose, are found in human milk but are not metabolised by gut enzymes and are instead broken down to a digestible form by bifidobacteria found in the intestinal systems of infants in a symbiotic process.
