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.

Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (âwater-lovingâ). Lipids, however, are hydrophobic (âwater-fearingâ). Some lipids are amphipathicâpart of their structure is hydrophilic and another part, usually a larger section, is hydrophobic.
