Question

Define the following terms:
(a) Denaturation of protein
(b) Invert sugar

Hint:

Denaturation of proteins does not affect their primary structure, but disrupts their secondary, tertiary, and quaternary structures, leading to loss of function.

Answer 1

(a) Protein Denaturation: - Denaturation is the loss of a protein's native structure caused by external influences like heat, altered pH, or organic solvents. - This disruption of secondary, tertiary, and quaternary structures leads to the protein's loss of biological function.

(b) Invert Sugar: - Invert sugar is a combination of glucose and fructose produced from the hydrolysis of sucrose. - Hydrolysis breaks down sucrose into its constituent monosaccharides, glucose and fructose, which reverses the optical rotation from dextrorotatory to levorotatory, hence the name "invert sugar."
