CAS 59-23-4

Galactose

Description:

Galactose is a monosaccharide, a simple sugar that is an important carbohydrate in biology. It is an aldohexose, meaning it contains six carbon atoms and an aldehyde group. Galactose is typically found in dairy products and is a component of lactose, the sugar present in milk. It exists in two anomeric forms, alpha and beta, which differ in the orientation of the hydroxyl group at the first carbon. Galactose is a white, crystalline solid that is soluble in water and has a sweet taste, although it is less sweet than glucose. It plays a crucial role in various biological processes, including the synthesis of glycoproteins and glycolipids, which are essential for cell recognition and signaling. In the human body, galactose is metabolized primarily in the liver, where it can be converted into glucose for energy. Its CAS number is 59-23-4, which uniquely identifies this compound in chemical databases. Overall, galactose is vital for numerous physiological functions and is a key component of various biomolecules.

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).
