Denaturation Guide, Meaning , Facts, Information and Description
Denaturation is a structural change in biomolecules such as nucleic acids and proteins, usually caused by heat, acids, basess, detergents, or certain chemicals such as urea.Proteins denature when they lose their three-dimensional structure and thus their characteristic folded structure. Enzymes lose their catalytic activity, because the substrates cannot bind to the active site any more. Some, but not all, proteins can regain their correct structure when the denaturing influence is removed.
The denaturation of nucleic acids such as DNA, also called melting, is the separation of a double strand into two single strands, which occurs when the hydrogen bonds between the strands are broken. Nucleic acid strands realign when "normal" conditions are restored.
Denaturation is also a term used for the adulteration of ethyl alcohol with methanol. By adding methanol to ethyl alcohol, it becomes unfit for human consumption, so companies that sell the alcohol are not subject to the same taxes they would be otherwise.
