Hint: Protein is a biological polymer whose monomer is amino acid. Amino acids are aliphatic carboxylic acids having one basic amino group and one acidic carboxylic group. All alpha amino acids have structures.
Complete Step by Step Solution:
Albumin is a simple protein made by our liver. It enters our bloodstream and helps to keep fluid from leaking out of our blood vessels.
Alanine is an alpha amino acid. The formula of the amino acid alanine is given as $C{{H}_{3}}-CH(N{{H}_{2}})-COOH$. Thus alanine contains both acidic and basic function groups such as amine and carboxylic group.
Insulin is a hormone that helps to control the sugar level of our blood.
The four major muscle proteins are myosin, actin, tropomyosin, troponin. Keratin is a protein that is present in our hair and nails.
Thus the correct option is $D$.
Note: Protein is the essential constituent of our body. We get the protein from various foods like meat, vegetables, fruits, nuts etc. Amino acids are the building blocks of the protein connected by peptide links. Protein is present in our muscles, hair, nails and other parts of the body.
