Proteins possess specific secondary, tertiary, and sometimes quaternary structures maintained by hydrogen bonds, ionic bonds, hydrophobic interactions, and disulfide linkages. When these forces are disrupted, the protein loses its natural conformation and biological activity. This process is known as denaturation. Denaturation can be caused by various physical and chemical factors. Heat is the most common cause, as high temperature increases molecular motion and breaks weak bonds. Acids and alkalis change the
