The denaturation of pepsin causes improper digestion and could lead to stomach infections. Heat Shock Proteins Denaturation can also cause biological responses such as heat shock proteins.

WebActive site amino acid residues often have acidic or basic properties that are important for catalysis. Changes in pH can affect these residues and make it hard for substrates to bind. Enzymes work best within a certain pH range, and, as with temperature, extreme pH values (acidic or basic) can make enzymes denature. WebDenaturation, such as the process of boiling an egg, causes a major phase change in proteins.Protein denaturation involves structural or conformational changes from the native structure without alteration of the amino acid sequence. These changes can be induced by pH, detergents, urea, and guanidine hydrochloride, as well as by heat.

WebDenaturation. For proteins, function is dependent on precise structure. Loss of the precise, folded structure of a protein is known as denaturation and is usually accompanied by loss of function. ...
