Galaktose

Beschreibung:

Galaktose ist ein Monosaccharid, ein Einfachzucker, der ein wichtiger Kohlenhydrat in der Biologie ist. Es ist ein Aldohexose, was bedeutet, dass es sechs Kohlenstoffatome und eine Aldehydgruppe enthält. Galaktose kommt typischerweise in Milchprodukten vor und ist ein Bestandteil von Laktose, dem Zucker, der in Milch vorhanden ist. Es existiert in zwei anomeren Formen, Alpha und Beta, die sich in der Orientierung der Hydroxylgruppe am ersten Kohlenstoff unterscheiden. Galaktose ist ein weißes, kristallines Feststoff, das in Wasser löslich ist und einen süßen Geschmack hat, obwohl es weniger süß ist als Glukose. Es spielt eine entscheidende Rolle in verschiedenen biologischen Prozessen, einschließlich der Synthese von Glykoproteinen und Glykolipiden, die für die Zellidentifikation und Signalgebung unerlässlich sind. Im menschlichen Körper wird Galaktose hauptsächlich in der Leber metabolisiert, wo es in Glukose zur Energiegewinnung umgewandelt werden kann. Seine CAS-Nummer ist 59-23-4, die diese Verbindung in chemischen Datenbanken eindeutig identifiziert. Insgesamt ist Galaktose für zahlreiche physiologische Funktionen von entscheidender Bedeutung und ist ein Schlüsselbestandteil verschiedener Biomoleküle.

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).
