Chemical denaturation of protein

Answer 1

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape.

Denaturation occurs because the bonding interactions responsible for the secondary structure (hydrogen bonds to amides) and tertiary structure are disrupted. In tertiary structure there are four types of bonding interactions between "side chains" including: hydrogen bonding, salt bridges, disulfide bonds, and non-polar hydrophobic interactions. which may be disrupted. Therefore, a variety of reagents and conditions can cause denaturation. The most common observation in the denaturation process is the precipitation or coagulation of the protein.

Answer 2

Denaturation is the loss of structure in proteins, destroying their binding sites and making them dysfunctional. Since proteins can only work in a specific environment, several things come into play. A drastic change in temperature, pH, or salt content can all affect the protein structure.

Answer 3

Proteins have hydrogen bonds in them to create their 3d shape. When there is a change in temperature or acidity of the environment of the protein, the hydrogen bond breaks and 'uncoils' the protein. So the protein is said to bedenatured. Since its shape has changed it cannot function anymore, whether its function isstructuralor hormonal.

Answer 4

When a protein is denatured, it means that its active site has been structurally changed. Denaturation will render the protein incapable of functioning.
