Question

The number of peptide bonds in the compound is :

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is B $2$

A peptide bond is a chemical bond formed between two molecules when a carboxylic group of one molecule reacts with an amino group of the other to form, thus releasing a water molecule.

The CO-NH bond is called a peptide bond.

In the given peptide chain the number of peptide bonds is 2 (shown in the above image by red mark).

Hence the correct option is B.
