• Beschreibung: 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).
