Question

Pulses are a good source of

a. Carbohydrates

b. Fats

c. Protein

d. Vitamin

Answer 1

Hint: There are different food items that are a rich source of energy and help in the bodybuilding and repair of the body. These are the polymers of amino acids.

Complete answer:

Pulses are a good source of Protein. It is due to the process of Biological Nitrogen fixation that rich amounts of nitrogen are supplied to the leguminous plants. Pulses belong to the legume family and form a symbiotic relationship between roots and bacteria like Rhizobium which helps in nitrogen fixation.

Additional Information:

Protein word is derived from the Greek word "proteious'  means first or foremost. The word was coined by Berzelius in 1837 and Mudler in 1838. They help in the formation of structural support, storage, transport, signaling, and movement, etc.

Proteins are the linear, unbranched polymers of amino acids. They are joined together with the help of a peptide bond.

They have four types of structures:

Primary Structure: When the amino acids are arranged linearly it is known as the primary structure.

Secondary Structure: When a very long chain of amino acids coil it is the secondary structure.

Tertiary Structure: When the chain coil in a manner to form a 3-dimensional structure is known as the tertiary structure.

Quaternary Structure: When two or more protein chains are combined together with bonds other than covalent bonds like hydrogen force or electrostatic force are known as quaternary structure.

Therefore, the correct answer is option (c), Protein.

Note:

- Proteins are linear chains of amino acids linked by peptide bonds.

- A peptide bond is a bond formed between Nitrogen atoms of the amino group and Carbon of the carboxylic acid groups.

- Proteins are classified on the basis of complexity. These are simple proteins and conjugated proteins.
