NEET · BiologyEasy
What is the primary linkage that connects amino acids in a protein chain?
- A.Glycosidic bond
- B.Peptide bond
- C.Phosphodiester bond
- D.Hydrogen bond
Show correct answer & step-by-step solution
Correct answer: B — Peptide bond
Solution
- Proteins are polymers of amino acids.
- The bond forms between the carboxyl group () and the amino group ().
- This specific covalent linkage is called a peptide bond.
- The reaction releases a water molecule.
- Hence the answer is (B).
