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: -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.

Detailed explanation-3: -Monomers are atoms or small molecules that bond together to form more complex structures such as polymers. There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides.

Detailed explanation-4: -Types of Amino Acids There are 21 amino acids present in proteins, each with a specific R group or side chain.

Detailed explanation-5: -Amino acids are known as protein monomers. They join a large number and connect through peptide bonds, which construct polypeptide chains. Large proteins are formed when two or more polypeptide chains are joined together. The sequence of amino acids decides the function and structure of a protein.
