Explain the structure of proteins?
Proteins have four different types of structure:-
1)Primary structure - single linear chain of amino acids.
2)Secondary structure-chain of amino acids forming helix or beta pleated sheet.
3)Tertiary structure - polypeptide chain form a complex 3D structure by forming a bonding between the amino acids.
4)Quarternary structure- two or more polypeptide chains are bonded together to form this structure.
