2-(Acetylamino)-2-deoxy-3-O-β-D-galactopyranosyl-D-galactopyranose

Description:

2-(Acetylamino)-2-deoxy-3-O-β-D-galactopyranosyl-D-galactopyranose, commonly referred to as a derivative of galactose, is a carbohydrate with notable structural features. This compound consists of two galactopyranose units linked through a glycosidic bond, with an acetylamino group at the 2-position of one of the sugar moieties. The presence of the acetylamino group enhances its solubility and reactivity, making it relevant in various biochemical applications. The β-D-galactopyranosyl configuration indicates that the hydroxyl group at the anomeric carbon is in the equatorial position, which is significant for its biological interactions. This compound may exhibit properties such as being a substrate for specific enzymes or serving as a building block in glycoprotein synthesis. Its CAS number, 20972-29-6, allows for precise identification in chemical databases. Overall, this substance is of interest in fields such as medicinal chemistry and biochemistry, particularly in the study of glycosylation and carbohydrate-protein interactions.

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.
