Although some whites reacted negatively to the spreading protests of 1963, Kingâs linkage of black militancy and idealism helped bring about passage of the Civil Rights Act of 1964. This legislation outlawed segregation in public facilities and racial discrimination in employment and education.
Physical Properties: Nonpolar. Leucine, an essential amino acid, is one of the three amino acid with a branched hydrocarbon side chain. It has one additional methylene group in its side chain compared with valine.Like valine, leucine is hydrophobic and generally buried in folded proteins.Close window.hysical Properties: Nonpolar.

The hydrophobic effect is the observed tendency of nonpolar substances to aggregate in aqueous solution and exclude water molecules.This occurs because interactions between the hydrophobic molecules allow water molecules to bond more freely, increasing the entropy of the system.The word hydrophobic literally means water-fearing, and it describes the segregation and apparent repulsion between water and nonpolar substances.The hydrophobic effect is responsible for the separation of a mixture of oil and water into its two components.his occurs because interactions between the hydrophobic molecules allow water molecules to bond more freely, increasing the entropy of the system.
