Explanation:

It should be noted that protein consist of amino acids. There are hundred of amino acids that are contained in protein. Examples of protein include fish, meat, eggs, nuts etc.

The amino acid sequence that can be found in the protein determines the primary structure of protein. The functions of protein include building and repair of body tissues, it also helps in maintain a proper potential of hydrogen (PH) for the body. Lastly, protein is also essential for growth as they help in cell and tissue growth.

Enzymes are catalysts that are responsible for speeding the chemical reaction rate in the body cells. Enzymes help in digestion.

Hemoglobin, is a protein that contains iron that can be found in the blood of animals. The function of the haemoglobin is to help in transferring oxygen to the tissues from the lungs.
