What is a peptide bond?
A protein is composed of a combination of amino acids. The amino acids join together in a peptide bond. A number of peptide bonds give polypeptides which are the building blocks for proteins.
Now, we can see from the image that the polypeptide bond occurs between the carboxylic group of the glycine and the amine group of the alanine.
This leads to a loss of water molecule and a subsequent formation of the amide bond by condensation.
