Galactose

Galactose (from Greek γάλακτος galaktos "milk"), sometimes abbreviated Gal, is a monosaccharide sugar that is less sweet than glucose. It is a C-4 epimer of glucose.

Galactan is a polymer of the sugar galactose found in hemicellulose. Galactan can be converted to galactose by hydrolysis.
