(Part a)

(Part b)

(Part c)

(Part d)

Step-by-step solution

Introduction(Part a) 

Proteins are constructed from amino acids. These have one hydrogen atom and one amine group.$\left(-{\mathrm{NH}}_2\right)$, one carboxylic acid group $(-\mathrm{COOH})$as well as one side chain (R group) connected to the central carbon atom

The carboxylic acid's hydroxyl group and the amino group's hydrogen combine to form a water molecule and an amide linkage. A "peptide bond" is an amide bond formed between the carboxylic group of one amino acid and the amino group of another amino acid.
