PPT-19.6 Protein Hydrolysis and Denaturation

Denaturation of a protein occurs when the interactions of residues that stabilize tertiary or quaternary structures are disrupted which destroys the shape and renders the protein biologically inactive.

Denaturation is a phenomenon that involves transformation of a well-defined, folded structure of a protein, formed under physiological conditions, to an unfolded state under non-physiological conditions.. o. f Burns.

Qualitative chemical reactions of amino acid protein functional groups: . -Certain functional groups in proteins can react to produce characteristically colored products. . -The color intensity of the product formed by a particular group varies among proteins in proportion to the number of reacting functional or free groups present and their accessibility to the reagent. .
