2.) An unknown amino acid was subjected to paper chromatography with five amino acid standards in order to identify it. After visualization using ninhydrin, the distances travelled were measured as follows: A B с D E X Distances: Solvent - 9.3cm A - 1.33cm B - 4.75cm C - 2.44cm D - 7.62cm E - 8.75cm X - 1.45cm a.) What is the Rf value of each amino acid sample? b.) Arrange the amino acids from most non-polar to least non-polar (include sample X). c.) What is the possible identity of the unknown amino acid? Answer can be up to two amino acids.
