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 hydrophobicity index is a measure of the relative hydrophobicity, or how soluble an amino acid is in water.In a protein, hydrophobic amino acids are likely to be found in the interior, whereas hydrophilic amino acids are likely to be in contact with the aqueous environment.he hydrophobicity index is a measure of the relative hydrophobicity, or how soluble an amino acid is in water.
