Amino acids placed on a cation-exchange resin containing sultfonate (-SOs flow down the column at different rates because of two factors that infuence their movement: (1) attraction between the sulfanate groups on the column and positively charged functional groups on interactions between amino acid side chains and the strongly the amino acids, and (2) hydrophobic backbone of the polystyrene resin. For each pair of amino acids listed, determine the order of elution from a cation exchanger in pH 7.0 buffer Amino Ad PairButes First Elutes Second Asp and Lys Arg and Met Ala and Glu Phe and Ser 0Previous Give up & View Solution Check Answer ) NextExt about us careers privacy policy terms of use contact us help MacBook Air

Explanation / Answer

The largest proteins always elute first while the smallest ones elute the last. Larger proteins are excluded from the interior of the gel bead so they have less available column space to travel. Essentially, they travel a shorter distance and elute first.
