NEET 2016 Phase 1 · ChemistryProtein structurePrevious Year Question
In a protein molecule various amino acids are linked together by:
Answer: (C) Peptide bond. \textbf{Answer:} (C) Amino acids in a protein are joined by peptide () bonds.
- A.-glycosidic bond
- B.-glycosidic bond
- C.Peptide bond✓
- D.Dative bond
Correct Answer
(C) Peptide bond
Solution & Explanation
\textbf{Answer:} (C) Amino acids in a protein are joined by peptide () bonds. \textbf{Solution:} A peptide bond is an amide linkage formed by condensation between the of one amino acid and the of the next, with loss of water. Glycosidic bonds link sugar units in carbohydrates, while a dative (coordinate) bond is an electron-pair bond donated by one atom — neither links amino acids in proteins.
