what is ionic-complementary peptides
The ionic self-complementary peptides have a pattern of alternating positive and negative charged amino acids (e.g. â + â + â + â +, â â + + â â + +, â â â â + + + +), thus forming stable Î² strand or Î² sheet structures which can subsequently self-assemble into nanofibers due to the electrostatic interaction.. There are some 20 natural amino acids. They are the building blocks for various peptides and proteins. All the amino acids have a similar structure: each consisting of an alpha carbon atom to which a hydrogen atom, an amino group, a carboxyl group, and a side chain R group are attached [1] .
