Amino acids relative size

  1. Sep 8, 2010 #1
    I need to compare amino acid R chains relative to each other. Is there a way to figure this out with the chemical forumula or am i supposed to glance over the stuctures?

    Also I am finding mixed messages about polarity for each. Are these correct?

    lab test rf theoretical rf
    Glycine .49 .26 Nonpolar
    Tryptophan .80 .66 Nonpolar H-bond
    Lysine .31 .14 Polar
    Aspartic Acid .42 .24 Polar
    Serine .44 .27 Polar
    Alanine .88 .38 Nonpolar
    Leucine .76 .73 Nonpolar
    tyrosine .69 .45 Non Polar

    No idea about polarities, yes you need structures.
