The process of protein denaturation Multiple Choice: a) is only possible in proteins with quaternary structure. b) is permanent and irreversible. c) changes the form of a protein, but not its function. d) is temporary and reversible.

Protein generally are very sensitive macro molecules; they have specific temperatures and pH that are ideal for their operations, this is especially true for proteins that act as enzymes in biochemical reactions.

There are four different types of structures that a protein can assume, these are primary, secondary, tertiary and Quaternary structure. The structure of a protein determines the kind of function it can perform.

There are some factors that can destroy the structure and functions of proteins, these include excessive heat and pH. A protein is said to be denatured when its secondary and tertiary structure have been disrupted or destroyed. Denaturation does not affect the primary structure of the protein, thus, the peptide bond remains intact.

Denaturation is usually temporary and can be reversed if the factors that cause denaturation is removed, this process is called RENATURATION. Renaturation process allow the protein to refold and resume its functions. But sometimes, denaturation can be permanent and irreversible leading to permanent loss of protein functions.
