Question

Proteins are biopolymers. Their monomeric units are:

• A. Carbohydrates
• B. Amino acids
• C. Fatty acids
• D. Alkenes

Answer 1

The correct option is B Amino acids

Proteins are bio-polymers formed by monomeric amino acids. Amino acids, in turn, are obtained by the hydrolysis of proteins.
The hydrolysis of proteins to amino acids is carried out in presence of base $[6N-NaOHorBa(OH{)}_2]$ or proteolytic enzymes.
The amino acids obtained can be separated by various physical techniques such as electrophoresis and paper chromatography.
