Nucleoside is the name for a nucleotide before it is attached to a phosphate group
Step-by-step explanation:
Cells and extracellular solutions in organisms include small concentrations of nucleosides, compounds of a base and a sugar outwardly a phosphate. Nucleotides are nucleosides that have one, two, or three phosphate groups esterified at the 5′ hydroxyl.
A nucleoside consists clearly of a nucleobase which is referred as nitrogenous base in general and a five-carbon sugar ribose whereas a nucleotide is comprised of a nucleobase, a five-carbon sugar, and more than one phosphate groups. Nucleosides are normally achieved by chemical or enzymatic decomposition of nucleic acids.
