The word oligosaccharide is formed from the Greek words oligo meaning few and saccharin meaning sugar. Oligosaccharide means few sugars. Carbohydrates that break down or break down into a few molecules of monosaccharides (3-10 molecules) are called oligosaccharides. Monosaccharides or monomers are linked by glycosidic bonds to form oligosaccharides. The attachment of the hydroxyl group of one monosaccharide to the hydroxyl group of another monosaccharide is called glycosidic linkage. Dr. Siddiq Publications
