First write what proteins are made of, their dynamic in nature, why these are not bioactive, why modifications, and how these can be made to be active. Please do not confuse and intervene bio-proteins in a human body. Let that be a separate section and then connect the bioactive proteins and peptides with the functions they perform in human body. You need to have structures of proteins and how these can be converted to peptides.
sequence of amino acids? Type of amino acids? Amount of specific amino acids for a particular function? Size of proteins, peptides?? Please consider these and others in the literature and give recent references.
Justify why and say why native protein molecules in general are not highly bioactive with references Please include the structure of a protein, unfolding and unfolded. Try to draw all your self.
