Starch glycosidic bonds
WebbStarch is a polymeric carbohydrate consisting of numerous glucose units joined by α-(1→4)-D glycosidic bonds. Description Starch is a type of polycarbohydrate, consisting of a large number of glucose units connected by glycosidic bonds. WebbSugars link together via a glycosidic bond to form di- (two monosaccharides) or oligo- (3 to 15 monosaccharides), and polysaccharides. The nature of glycosidic bonds influences the structural and chemical properties of the sugars and influences their ease of digestion. Sugars that bond via an alpha 1,4 linkage may be digested by mammalian enzymes.
