2-(Acetilamino)-2-desossi-3-O-β-D-galattopiranosil-D-galattopiranosio

Descrizione:

2-(Acetilamino)-2-desossi-3-O-β-D-galattopiranosil-D-galattopiranosio, comunemente riferito come un derivato del galattosio, è un carboidrato con caratteristiche strutturali notevoli. Questo composto è costituito da due unità di galattopiranosio collegate tramite un legame glicosidico, con un gruppo acetilamino nella posizione 2 di uno dei moieties di zucchero. La presenza del gruppo acetilamino ne migliora la solubilità e la reattività, rendendolo rilevante in varie applicazioni biochimiche. La configurazione β-D-galattopiranosil indica che il gruppo idrossile nel carbonio anomerico è in posizione equatoriale, il che è significativo per le sue interazioni biologiche. Questo composto può presentare proprietà come essere un substrato per enzimi specifici o fungere da mattoncino nella sintesi di glicoproteine. Il suo numero CAS, 20972-29-6, consente un'identificazione precisa nei database chimici. In generale, questa sostanza è di interesse in campi come la chimica medicinale e la biochimica, in particolare nello studio della glicosilazione e delle interazioni carboidrato-proteina.

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.
