denaturation [de-na″chur-a´shun]

a change in the usual nature of a substance, as by the addition of methanol or acetone to alcohol to render it unfit for drinking, or the change in the physical properties of a substance, such as a protein or nucleic acid, caused by heat or certain chemicals that alter tertiary structure.

protein denaturation any nonproteolytic change in the chemistry, composition, or structure of a native protein that causes it to lose some or all of its unique or specific characteristics.

denaturation

1. a change in the usual nature of a substance, as by the addition of methanol or acetone to alcohol to render it unfit for drinking.

2. in proteins and nucleic acids produced by heat or certain chemicals, usually results in loss of function. In proteins, various noncovalent bonds are disrupted resulting in unfolding of the polypeptide chain; in nucleic acids hydrogen bonds between nucleotides are disrupted converting double-stranded molecules or parts of them into single-stranded forms.
