2. Illustrate a glycosidic, peptide and a phospho-diester bond.

Answers (1)

Glycosidic bond- This bond is formed between the 1st carbon atom of one monosaccharide with 4 carbon atom of neighbouring monosaccharide unit. During the formation of this bond, a water molecule is released. A representation of a glycosidic bond is as follows

 

Peptide bond- This is a covalent bond formed between the carboxyl group of one amino acid and the amino group of neighbouring amino acid. A water molecule is released in the formation of a peptide bond. A representation of a peptide bond is as follows

Phosphodiester bond- It refers to the phosphate-hydroxyl linkage between two nucleotides. In this bond, the phosphate attached to the hydroxyl group at the 5' carbon of pentose sugar is in turn bonded to the hydroxyl group of the 3' carbon of the pentose sugar of the next nucleotide.
