Mixtures of amino acids can be analyzed by first separating the mixture into its components through ion‑exchange chromatography.
Amino acids placed on a cation‑exchange resin containing sulfonate (−SO−3)(−SO3−) groups flow down the column at different rates because of two factors that influence their movement: (1) ionic attraction between the sulfonate residues on the column and positively charged functional groups on the amino acids, and (2) aggregation of nonpolar amino acid side chains with the hydrophobic backbone of the polystyrene resin.
Note that the ionic attraction is more important than hydrophobicity for this column media.
For each pair of amino acids, identify which will be eluted first from a cation‑exchange column using a pH 7.0pH 7.0 buffer.
Cysteine is converted to cystine which is readily transported into mammalian cells. In the cells, cystine is converted back to cysteine, an essential amino acid needed to synthesize biomolecules such as proteins, or Coenzyme A3. What reagents would you choose to make the disulfide bond in the lab? Choose all that would produce the disulfide bond.
