Nucleotide

Name:
Nucleotide
Detailed information:
A fundamental unit of nucleic acids; some are important coenzymes. The four nucleotides found in nucleic acids are phosphate mono-esters of nucleosides, adenylic acid, guanylic acid, uridylic acid, and cytidylic acid. Great progress has been made in determining the nucleotide sequence in fundamental materials, such as yeast genes.The term is also applied to compounds not found in nucleic acids and that contain substances other than the usual purines and pyrimidines. Such compounds are modified vitamins and function as coenzymes; examples are riboflavin phosphate (flavin mononucleotide), flavin adenine nucleotide, nicotinamide adenine dinucleotides, nicotine adenine dinucleotide phosphate, and coenzyme A. The nucleotides inosine-5′-monophosphate and guanosine-5′-monophosphate are used as flavor potentiators.
