Detailed Description

amino acid residue building block for protein polypeptide chain molecules

AminoAcidResidue has three unsatisfied BondCenters: 1) "bondN" at the amino nitrogen, for the preceding amino acid residue 2) "boncC" at the carbonyl carbon, for the next amino acid residue 3) "bondCA" at the alpha carbon, for the side chain

The decision of which atoms bond to bond centers bond1, bond2, bond3 etc., depends upon several criteria: 1) chirality - in quadravalent atoms (e.g. alpha carbon), bonds 2, 3, 4 are aranged clockwise when viewed down bond 1. 2) inboard bond - unless explicitly changed, bond1 is the inboard bond for a given compound 3) dihedral angle definition - the dihedral angle for bond1 is defined relative to the plane containing bond2. bonds2,3,4... are defined relative to bond1
