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. 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.
Role in function: The Leucine side chain is very non-reactive, and is thus rarely directly involved in protein function, though it can play a role in substrate recognition. In particular, hydrophobic amino acids can be involved in binding/recognition of hydrophobic ligands such as lipids.Back to main page.ole in function: The Leucine side chain is very non-reactive, and is thus rarely directly involved in protein function, though it can play a role in substrate recognition.
