Question

What is the reason behind getting only one peptide bond from two to perform a functional protein?

Answer 1

To make a protein, amino acids are connected together by a type of amide bond called a “peptide bond”.& This bond is formed between the alpha amino group of one amino acid and the carboxyl group of another in a condensation reaction. When two amino acids join, the result is called a dipeptide, which can be actually functionally active (vilon, timogen). The minimum size of a protein is defined as about 50 residues; smaller chains are referred to simply as peptides.
