Answer : The correct option is, peptide bond.
Explanation :
- Amino acid : Amino acid are the acid that contains two functional groups which are carboxylic group, [tex]-COOH[/tex] and ammine group, [tex]-NH_2[/tex].
When the several amino acids join together with the help of peptide bond, they produce polypeptide chain or protein. The bond present between the two amino acid is a peptide bond. The peptide bond is formed between the nitrogen of one amino acid and carbon of another amino acid.
- Covalent bond : It is formed between the two non-metal element.
- Ionic bond : It is formed between the one metal and non-metal element.
- Hydrogen bond : It is formed between the proton of one molecule and the electronegative atom of another molecule.
