Step by step solution

01

Introduction (Part a) 

Amino acids contain an amine-NH2and carboxylic acid localid="1653136346654" (-COOH)functional group. Both the functional groups are covalently bonded to the a-carbon. Amino acids are the building blocks for all proteins. When two amino acids react, an amide bond is formed between the amine group of one amino acid and the carboxylic group of the other amino acid, which joins the two amino acids. Proteins are macromolecules composed of repeating subunits known as amino acids, which determine protein shape and function.
