| how is a disaccharide formed? | linking of 2 sugars by an O-glycosidic bond |
| transpeptidase? | catalyses final step in cell wall biosynthesis, cross linking of peptidoglycan |
| cellulose? | isomer of alpha-amylose beta glycosidic links inverted flip 180 interval to facilitate formation of glycosidic link |
| lactose? | 1,4-glycosidic link |
| describe linkages in hyaluronate | 250-25000 beta1-4 linked disaccharide units consiisting of D-glucuronic acid and N-acetyl-D-glucosamine linked by a beta 1-3 bond |
| how is sucrose a non-reducing sugar? | 1-2 glycosidic bond takes up both anomeric carbons so disaccharide cannot open so cannot react with reducing agents |
