What is a glycosidic linkage
The covalent bond which joins the hemiacetal group of a saccharide and hydroxyl group of
another molecule(may or may not be saccharide ) is called glycosidic Bond.
The common atom which joins the two groups can be oxygen(O), Nitrogen(N) and Sulfur(S)
so the name of the bond becomes O-glycosidic Bond and N-glycosidic Bond and S- glycosidic Bond respectively.
There is the linkage between the hemiacetal group of the saccharide and some other group and this link is called glycosidic linkage.
