1. Glycans usually consist solely of O-glycosidic linkages of monosaccharides. 2. These enzymes can break glycosidic linkages by using a water molecule. 3. Liberation of ginkgotoxin by enzymatic hydrolysis of the glycosidic linkage is possible. 4. Oligosaccharides are linear or branched chains of monosaccharides attached to one another via glycosidic linkages . 5. The serine and threonine hydroxyl groups link to the polypeptide chains via O-glycosidic linkages . 6. In a nucleoside, the base is bound to either ribose or deoxyribose via a glycosidic linkage . 7. Glycogen phosphorylase can act only on linear chains of glycogen ( ?1-4 glycosidic linkage ). 8. After removal of the fat from the resulting gum, the glycosidic linkage is recrystallized from anhydrous acetone. 9. The units are joined by alternating ?-1, 3 and ?-1, 4 glycosidic linkages . 10. ThumbThree angles are described by ?, ? and ? ( in the case of glycosidic linkages via O-6 ).
