Answer:
Each protein with a specific structure and function
The unique three dimensional shape of proteins is based on several superimposed levels of structure
Explanation:
Proteins are essential nutrients for human and a vital source of fuel for building body tissues. They are made up of amino acids linked together by peptide bonds. These amino acids act as precursor to nucleic acids, hormones, immune, repair of tissues among others.
Proteins contain 20 amino acids which are the building block for proteins. These amino acids can be reformed to create millions of protein in human body in which each protein has specific structure and function.
The three dimensional arrangement of atoms in an amino acid chain is know as the protein structure. The precise shape formed determine the protein function.
