Question

Amino acid in a polypeptide are joined b________ bond

Answer 1

Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).

Explanation:

Answer 2

Amino acid in a polypeptide are joined by peptide bond.

• A peptide bond is an amide bond which is formed between the carboxyl group of one amino acid and the amino group of other amino acid to form a peptide.
• During the formation of peptide bond, water molecules are released. This is why it is also known as a dehydration reaction.
• A chain containing two amino acids linked by a peptide bond is called dipeptide.
