Question

The bond between two amino acids in protein chain is

• A. Hydrogen bond
• B. Peptide bond
• C. Glycosidic bond
• D. Phosphodiester bond

Answer 1

The correct option is B Peptide bond

Hydrogen bond is formed by H attached to any highly electronegative atoms (like -$F,O\text{and}N$).
The bond between two amino acids in protein chain is called peptide bond.
Monosaccharides are bonded by glycosodic linkage to form disaccharides or polysaccharides.
Nuceic acid(DNA and RNA) chains are formed by phosphodiester bond between two nucleotide units.
