NEET2015BotanyBiomolecules (B)Actual
Which of the following biomolecules does have a phosphodiester bond?
Options
- AMonosaccharides in a polysaccharide
- BAmino acids in a polypeptide
- CNucleic acids in a nucleotide
- DFatty acids in a diglyceride
Correct answer
C. Nucleic acids in a nucleotide
Step-by-step solution
Phosphodiester bond is formed between two nucleotides of nucleic acid. A phosphodiester bond occurs when exactly two of the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. Proteins have presence of peptide bond or amide linkage, carbohydrates have glycosidic bond or ether linkage, while lipids have presence of ester bonds.
