Nucleotide: A nucleotide is formed when one molecule of nucleoside unites with one molecule of phosphate.
Adenosine monophosphatc is united with a phosphate to form an adenosine diphosphate.
Again, an adenosine diphosphate being united with one molecule phosphate to form one molecule of adesine triphosphate.
Guanosine tri phosphate (GMP, GNIP+P- GDP, GDP+P- GTP)
Cytidine tri-phosphate (CMP, CMP+P- CDP, CDP+P- CTP)
Functions of Nucleotide:
- it creates the main frame work of DNA and RNA.
- It plays the key role in protein synthesis, intermediate metabolism, respiration and phospholipids synthesis.
