Interpretation:
The term proteins and the portion of the human body consists of proteins needs to be explained.
Concept introduction:
Proteins- proteins are the complex substance that covers the huge portion of the living organism. Proteins are composed of a large chain of amino acids. Proteins of similar functions have similar amino acid composition and sequence.
In the human body breaks down and consumed protein into amino acids, and absorbs it. It is used to build muscles and organs.

Answer to Problem 2A
Proteins are made up of amino acids. They are known as building blocks for the human body.
Explanation of Solution
Protein is a naturally occurring organic compound. It is a macronutrient that is essential to form the major portion of the muscle mass. Proteins are composed of amino acids. These organic compounds are made of carbon, hydrogen, nitrogen, oxygen, or sulfur. Amino acids are the monomer of proteins, and proteins are the building blocks of muscle mass,
The main portion of the human body is consists of proteins such as muscle, bone, organs, skin, nails. So it is known as the building block for the human body.
Proteins are among the higher abundant organic compound in living systems, it is composed of the amino acid. The amino acid is known as a monomer for the proteins. Proteins play a major role to form the infrastructure of the human body.
