What is the effect of denaturation on the structure of proteins?
Denaturation refers to the process where the secondary or tertiary structure of proteins gets disturbed. This alteration in structure is typically caused by a change in pH or temperature.
When denaturation occurs, the natural folding of the protein chain, such as the helix or the hollow woolen ball shape, is disrupted. As a result of this disturbance in the three-dimensional view, the proteins lose their biological properties. Consequently, they are not able to perform their functions within the organism.
Explanation
The answer is derived directly from the textbook context which defines denaturation. The text states that 'The secondary or tertiary structure of proteins get disturbed on change of pH or temperature and they are not able to perform their functions. This is called denaturation of proteins.' The answer synthesizes this definition with the structural descriptions provided in the 'Structure of Proteins' section regarding secondary (helix) and tertiary (hollow woolen ball) structures.
