A bond formed by linkage between -OH of carboxyl group of one amino acid and H of amino group of another amino acid which releases water is called__________?
Correct answer: C. Peptide bond
- A. Phosphodiester linkage
- B. Glycosidic bond
- C. Peptide bond
- D. Hydrogen bond
Explanation
A peptide bond forms when the carboxyl group of one amino acid reacts with the amino group of another, releasing one molecule of water and producing a C-N linkage. The likely mistake is choosing a hydrogen bond, which is a weak attraction involved in protein shape rather than the covalent bond joining amino acids.
