A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. A nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups.Nucleoside = Sugar + Base. Nucleotide = Sugar + Base + Phosphate.ugar + Base. A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. When phosphate group of nucleotide is removed by hydrolysis, the structure remaining is nucleoside. Sugar + Base + Phosphate.
The second part of a nucleotide is the phosphate, which differentiates the nucleotide molecule from a nucleoside molecule. This phosphate is important in the formation of phosphodiester bonds, which link several nucleotides in a linear fashion. The third part of a nucleotide is the pentose (5 carbon) sugar.
