Proteins are made up of Amino acids. Complex proteins contain various kinds of protein molecules linked together by non covalent bonds.
Complex proteins have quaternary structure.
The primary protein contains a polypeptide chain.
Secondary proteins have beta sheet or Alpha helix shape.then further foldings gives us tertiary protein.
When this tertiary protein is bonded with a non protein moiety we get a complex quaternary protein.
Final Answer:-
Proteins are made up of amino acid molecules .In the primary structure of protein contains polypeptide chains. These chains combined to give us a beta sheet or Alpha helix structure.
From the secondary structure we get tertiary structure by further folding and when the situation is bonded with a non – protein moiety we get complex proteins.
