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.

Isoleucine (abbreviated as Ile or I) is an Î±-amino acid which is essential in humans (it cannot be synthesized, so it must be ingested). The iso-in its name refers to it being an isomer of leucine.Its chemical formula is HO 2 CCH(NH 2)CH(CH 3)CH 2 CH 3.Its codons are AUU, AUC and AUA.ith a hydrocarbon side chain, isoleucine is classified as a hydrophobic amino acid. Together with threonine, isoleucine is one of two common amino acids that have a chiral side chain. Four stereoisomers of isoleucine are possible, including two possible diastereomers of.
