Question
Give primary information about the protein compounds.

Answer

Protein are the most abundant biomolecules of the living system.
Chief sources of proteins are milk, cheese, pulses, peanuts, fish meat etc. They occur in every part of the body and form the fundamental basis of structure and functions of life.
They are also required for growth and maintenance of the body.
The word protein is derived from greek word "Proteios" which means primary or of prime importance.
All proteins are polymers of $\alpha$ - amino acids.
