Proteins, which have diverse functions and a cell, are all polymers of the same kinds of monomers-amino acids. Describe how the structure of amino acids allow proteins to perform so many functions.

Proteins, which have diverse functions and a cell, are all polymers of the same kinds of monomers-amino acids. Describe how the structure of amino acids allow proteins to perform so many functions.

Step 1

Proteins are heteropolymers of amino acids. A protein is made up of different kinds of monomers (amino acids). The adjacent amino acids are linked together by peptide bonds. A water molecule is released at the time of peptide bond synthesis.

Step 2

The first amino acid is present at the N-terminal end (left end) while the last amino acid is present at the C-terminal end (right end). The polypeptide chain having more than 50 amino acids is called a protein.

Step 3

Proteins have four types of structures:

  • The primary structure of a protein refers to the linear sequence of amino acids. It is formed by the genetic information present on the DNA (deoxyribonucleic acid).
  • The secondary structure of the protein is stabilized by the hydrogen bonds. The linear polypeptide chain may fold into an alpha helix manner (keratin) or beta plated sheets (fibroin of silk).
  • Tertiary structures a...
