Nucleotide and Nucleoside
Q1: What are nucleotides and nucleosides?
Answer:
Nucleosides is a basic component of nucleotide composed of a nitrogenous base and a ribose/deoxyribose sugar linked together by a β-glycosidic bond, whereas the nucleotide is a structure comprised of nucleoside and an inorganic phosphate group attached to the C5′ of ribose sugar with phosphodiester bond.
Q2: Is ATP a nucleotide or nucleoside?
Answer:
ATP stands for Adenosine triphosphate, the name itself suggests that the phosphate group is attached to the sugar. so it should be considered as a nucleotide.
Difference Between Nucleotide and Nucleoside
Difference Between Nucleotide and Nucleoside: Nucleotides and nucleosides are nitrogenous bases with ribose sugar attached through a glycosidic bond. Therefore, a nucleoside is a nitrogenous base with ribose sugar attached through an β-glycosidic bond. In contrast, a nucleotide is a nucleoside with a phosphate group attached to ribose sugar through a phosphodiester bond.
