Explanation / Answer

The hydrophobic regions of a protein will cluster in the innermost portions of the protein's structure  if the protein was placed in a jar containing organic compound.

Explanation: This effect is called as "hydrophobic effect" in protein folding, which describes the abillity of hydrophobic/ non polar regions of proteins to interact with each other rather than with water. This interaction leads to their cluster in the interior of proteins. which in turn leads to collapse of the proteins from extended coil to a more compact globular structure. The non polar regions of proteins ( having phenylalanine, leucine, isoleucine, valine, methionineand tryptophan) tend to cluster in the interior of the protein while polar regions (having arginine, glutamine, glutamate etc) arrange themselves near the outside of molecule to form hydrogen bond with polar compounds.
