WebMar 5, 2024 · Fibrous proteins do not dissolve in water due to the difference in polarity. According to chemical laws, "like dissolves like". Since water is polar, and the surface of fibrous proteins is covered in non-polar amino acids, it does not dissolve into the aqueous solution. Explanation of Polarity: Polarity is the distribution of charges throughout ... The dissociation constant is commonly used to describe the affinity between a ligand (such as a drug) and a protein ; i.e., how tightly a ligand binds to a particular protein. Ligand-protein affinities are influenced by non-covalent intermolecular interactions between the two molecules such as hydrogen bonding, electrostatic interactions, hydrophobic and van der Waals forces. Affinities can also be affected by high concentrations of other macromolecules, which causes macromolecula…
