Answer: Glycosidic bonds.
Explanation:d
Glycosidic bonds are covalent bonds that join monosaccharides or longer glucose chains to other monosaccharide or carbohydrates to form disaccharides, oligosaccharides and polysaccharides and are named according to the type of the atom present on the second carbohydrate to be linked. The bond is usually formed between the hemiacetal of the first carbohydrate and the functional group on the second molecule which could be Oxygen-, Nitrogen-Sulphur -, and Carbon -glycosidic bonds.
Examples of Polysaccharides are Cellulose Starch , Glycogen formed by the linkage of many long residue monosaccharides connected through glycosidic bonds.
