WebSep 7, 2011 · Here, the C1 -OH is axial whereas the C4 -OH in glucose is (always is, by definition in "glucose") equatorial. The angle of this alpha 1,4 bond is such that the polymer bends at each glycosidic connecting bond, as can bee seen in handout 2-9, disaccharides in chair form. As a result, it takes on a helical shape that again allows lots of ... WebFor this trisaccharide, indicate whether each glycosidic linkage is α or β. Solution The glycosidic linkage between sugars 1 and 2 is β because the bond is directed up from the anomeric carbon. The glycosidic linkage between sugars 2 and 3 is α because the bond is directed down from the anomeric carbon.
