STRUCTURE OF PROTEINS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What factors can affect protein structure?
A
pH
B
temperature
C
alcohol
D
light
Explanation: 

Detailed explanation-1: -The main forces that affect structure are electrostatic forces, hydrogen bonding forces, hydrophobic forces, and disulfide bonds.

Detailed explanation-2: -Alcohol. Alcohol also denatures proteins. It does this the same way as heat, by breaking the bonds that hold parts of the protein in a folded shape. Sometimes the alcohol molecules bond directly to some of the parts of the protein, disrupting the normal way the protein would bond to itself.

Detailed explanation-3: -Posted June 22, 2020. Alcohol denatures a protein mainly by disrupting the intramolecular hydrogen bonding between the side chains, which is essential to maintain the tertiary protein structure.

Detailed explanation-4: -Protein Stability The interactions that hold proteins in their shape, like hydrogen bonds, can be affected by many factors. These include solvent, pH, salinity (how much salt is present), temperature, and the presence of other molecules.
