Question

Which of the following statements about proteins is not true?
A. Amino acid residues join together to make a protein molecule
B. Proteins are polymers with formula ${{({{C}_{6}}{{H}_{10}}{{O}_{5}})}_{n}}$
C. Eggs are richer in proteins
D. Pulses are good source of proteins ​

Answer 1

Hint: Protein is a naturally occurring and extremely complex substance that consists of amino acid residues. Proteins are present in all living organisms. Protein is the most important essential constituent of diet because protein is the main food for bodybuilding.

Complete Step by Step Solution:
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.
As amino acids are the building block of protein so, the simplest molecular formula of protein is $C{{H}_{3}}-CH(N{{H}_{2}})-COOH$

Proteins do most of the work in cells and they are required for the function, structure, and regulation of the tissues and organs of the body. Protein present in muscle of the body.
Protein is the essential constituent of many foods. Protein is present in milk, meat, fish, poultry, eggs etc animal based foods. Protein again present in vegetables, fruit, beans, nuts, grains, seeds, pulses etc plant based foods. We consumed protein which is essential for our body from these plant and animal based foods. Thus eggs are richer in protein and the protein present in eggs is albumin. Pulses are also a good source of protein.
Thus the correct option is B.

Note: Protein is present in hormones, enzymes etc. Again it is the main constituent of nails, skin, hair and other body tissues. Protein contains amino acid residues. It is the essential constituent of our diet. It performs many biological functions of our body.
