If the zwitterionic amino acids that wash through the column are polymerized into

If the zwitterionic amino acids that wash through the column are polymerized into, say, tripeptides and tetrapeptides, they will then bind to the column. Explain why converting individual amino acids into polypeptide sequences would be expected to enhance their affinity to a reversed phase column.     https://www.studyhelpus.com/Questions & Answers/zwitterionic/
