Encyclopedia > Glycosidic linkage

A glycosidic bond is formed between a hemiacetal group of a sugar molecule (such as glucose) and an alcohol functional group to form an acetal.


A N-glycosidic bond is formed between the hemiacetal group of a sugar molecule (such as ribose) and a N-H group on an aromatic ring. An example of this is the bond between a nucleobase and the deoxyribose molecule in DNA.


A glycosidic bond can also connect two monosaccharides, such as the linkage of glucose and fructose to create sucrose. It is simply the dehydration reaction between the hydroxide on the right edge of one sugar to the hydroxide on the left edge of the other sugar. A water molecule is extracted (causing a dehydration reaction), and a bond is formed, leaving an oxygen atom between the two monosaccharides, and creating a disaccharide.

The linkage of carbohydrate to 5-hydroxylysine is either the single sugar galactose or the disaccharide glucosylgalactose.
Linkage of carbohydrate to cytosolic and/or nuclear proteins occurs via O-linkage and involves attachment of GlcNAc to serine or threonine residues.
Some glycoproteins are tethered to the membrane by a lipid linkage: the protein is attached to the carbohydrate through phosphatidylethanolamine (PE) linkage, and the carbohydrate is in turn attached to the membrane via linkage to phosphatidylinositol (PI), which anchors the structure within the membrane.

Conformation of the glycosidic linkage in a disaccharide investigated by double-quantum solid-state NMR
The evolution of the double-quantum coherences is found to be consistent with the solid-state conformation of the molecule, as previously determined by X-ray diffraction.
