Classify these amino acids as acidic, basic, neutral polar, or neutral nonpolar.
Acidic: glut acid
Basic: Arg, Lys
Neutral polar: serine, asp, cys, glut, threonine
Neutral nonpolar: alanine, proline, meth, phenyl, valine, tyrosine, trypto
When transaminated, the three branched-chain amino acids (valine, leucine, and
isoleucine) form compounds that have the characteristic odor of maple syrup. An
enzyme called α-keto acid dehydrogenase converts these compounds into CoA
esters. Give the structure of the valine-derived compound that smells like maple
syrup.
Select the generic nonpolar amino acid that is in the correct form at
pH=7.0pH=7.0, or at physiological conditions. Pay close attention to the charges
on the amino group and the carboxylic acid group.
Draw L-aspartic acid as it would occur at the pHpH of most body fluids.
Match the amino acid (AA) with its correct side chain category:
1:D; 2:C; 3:F; 4:E; 5:B; 6:A
