CAS: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).Fórmula:C6H12O6Pureza:Min. 98 Area-%Cor e Forma:White PowderPeso molecular:180.16 g/molD-Galactose non-animal origin
CAS: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.
