What are isobars?

A mixture containing five amino acids (Ala, Asp, Gly, Phe, Pro) was analyzed using two methods of planar chromatography, paper and cellulose-coated thin layer. The solvent system was n-propanol/water (70/30 v/v). Predict the order of the mobility of the amino acids (low to high ) on the chromatograms.
