How can enzymes become denatured

Web1 INTRODUCTION. Enzyme stability is greatly influenced by the presence of water (Klibanov, 1989; Zaks and Russel, 1988). For example, the stability of α-amylase dissolved in water is very poor especially in low concentration without buffer. Many researchers focus on the methods that can promote the stability of enzymes. WebEnzymes are biological catalysts which speed up reactions. They are specific for their substrate. The lock and key hypothesis models this. Enzymes are denatured at …
