Welcome to Amino Acids Composition page of CPPsite 2.0

This page is designed for searching peptides with desired amino acids composition. Here, you may select composition range for an amino acid. For example, if you wish to know all cell penetrating peptides having more than ten percent composition of alanine then you may select minimum value for alanine as 10. One of the major features of this page is that its output composition table can be sorted on the basis of composition of any amino acid. For more information see HELP page.
