Detailed explanation-1: -For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein (Figure 1).

Detailed explanation-2: -There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides. Each of these monomer types play important roles in the existence and development of life, and each one can be synthesized abiotically.

Detailed explanation-3: -Explanation: Amino acids are the building blocks of proteins, and have an amine group (−NH2), as well as a carboxyl group (−COOH) . When hundreds and thousands of them combine using peptide bonds, they form proteins, which are nutrients essential for survival. So, we can say that amino acids are monomers of proteins.
