Cytidine monophosphate is nucleotide and can be written as C9H14N3O8P and these nucleotides comprises of 3 parts; phosphate group, sugar of 5C and a nucleobase.
Sugar can be either ribose or deoxyribose. DNA is made from the deoxyribose sugar and RNA from ribose sugar. The components of nucleic acids are the nucleotides.
The nucleic acid backbone is formed from phosphate and the sugar molecule and the synthesis takes place in 5’-3’ direction, although the two strands run in the opposite direction, so that they can bond with each other due to complementary bases.
Nucleotides can be linear as well as in cyclic form, where the phosphate group is bounded to the hydroxyl group of sugar. Phosphate group and nucleotide forms nucleoside.
Thus, to the sugar molecule, when a single phosphate group is attached it is called as nucleoside monophosphate and when two phosphate groups, it is called as nucleoside diphosphate and similarly when 3, it is called as nucleoside triphosphate.
Nucleoside can be deoxyribonucleoside or ribonucleoside. On the basis of pentose sugar, thus ribonucleoside consists of ribose sugar with nucleoside and these nucleosides can be adenine, guanine, cytosine and thymine.
Similarly, deoxyribonucleoside may have nucleosides like adenine, guanine, cytosine and thymine, in which adenine pairs with thymine and cytosine with guanine.
Pyrimidine and purine are two types of nucleoside where pyrimidine is single stranded and purine is double stranded.
