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.

Less hydrophobic amino acids, or indifferent amino acids: Amino acids that are part hydrophobic (i.e. the part of the side-chain nearest to the protein main-chain): Hydrophobic amino acids are those with side-chains that do not like to reside in an aqueous (i.e. water) environment.For this reason, one generally finds these amino acids buried within the hydrophobic core of the protein, or within the lipid portion of the membrane.
