Galattosio

Descrizione:

Galattosio è un monosaccaride, uno zucchero semplice che è un carboidrato importante in biologia. È un aldoesoso, il che significa che contiene sei atomi di carbonio e un gruppo aldeidico. Galattosio si trova tipicamente nei prodotti lattiero-caseari ed è un componente del lattosio, lo zucchero presente nel latte. Esiste in due forme anomeriche, alfa e beta, che differiscono nell'orientamento del gruppo idrossile al primo carbonio. Galattosio è un solido bianco e cristallino che è solubile in acqua e ha un sapore dolce, anche se è meno dolce del glucosio. Svolge un ruolo cruciale in vari processi biologici, inclusa la sintesi di glicoproteine e glicolipidi, che sono essenziali per il riconoscimento e la segnalazione cellulare. Nel corpo umano, Galattosio viene metabolizzato principalmente nel fegato, dove può essere convertito in glucosio per energia. Il suo numero CAS è 59-23-4, che identifica univocamente questo composto nelle banche dati chimiche. In generale, Galattosio è vitale per numerose funzioni fisiologiche ed è un componente chiave di varie biomolecole.

D-Galactose - non-animal origin

CAS: 59-23-4

D-Galactose is a monosaccharide that is found in the form of a white, odorless powder. It has many applications, including as an additive in foods and beverages, as an intermediate in the production of other modified sugars, and as an important component of glycoproteins. D-Galactose is also used to produce glycogen or lactose by modifying it with phosphate or acetate groups. The synthesis of D-galactose is done by methylation of D-glucose followed by glycosylation reactions. This product can be custom synthesized to meet your needs.

D-Galactose non-animal origin

CAS: 59-23-4

D-Galactose is a monosaccharide that is found in the cells of plants and animals. It can be synthesized from D-glucose by adding a D-galactose molecule to the alpha carbon of an existing glucose molecule. The resulting bond is called a glycosidic linkage. This process is called glycosylation. Glycosylation occurs when a sugar molecule reacts with another molecule, such as an amino acid, lipid, or nucleotide, to form what is known as a glycoside linkage. In this case, the sugar is D-galactose and the other molecules are either amino acids or lipids. The reaction between D-galactose and other molecules often results in polysaccharides and complex carbohydrates such as cellulose, chitin, and glycogen.
Methylation of D-galactose can produce methyl galactoside (CAS No. 1881-42-7), which

D-Galactose - anhydrous

CAS: 59-23-4

Galactose (Gal) is the C4 epimer of glucose with one hydroxyl group axial which by Hudsons rules makes it slightly less stable than glucose (Hudson, 1948). However, galactose is very common in plants and animals, and occurs in many polysaccharides, such as, galactomannans (e.g. Guar, Locust Bean Gum), Carrageenans , Agar (L-Galactose), Hemicellulose, Gum Arabic [link] and galactans (e.g. from Lupin) (Whistler, 1993). Galactose is one of the key mammalian monosaccharides (glucose, galactose, mannose, fucose, N-acetyl glucosamine, N-acetyl galactosamine and sialic acid) and it occurs in blood, milk, gangliosides, N- and O-linked glycans (Gabius, 2009). Like glucose, galactose exhibits mutarotation (Acree, 1968) and is optically active (dextrorotary) with L-galactose as its enantiomer (levorotary).
