Calculations on paper chromatography of peptides.

Knight has recently studied the movement of nineteen amino acids and thirty-four peptides on paper chromatograms (1). It seemed possible that from these data a general method of calculating the movement of a peptide relative to the movement of the solvent front (RI) could be obtained. Such calculations have been attempted in a simple, straightforward manner without utilizing any special factors for particular amino acids. The results are presented herewith, together with a discussion of some of the limitations of the method.
