Descriptors calculated from a specific representation scheme encode only one part of the chemical information. For this reason, there is a need to construct novel graphical representations of proteins and novel protein descriptors that can provide new information about the structure of proteins. | TOMOCOMD-CAMPS and protein bilinear indices - novel bio-macromolecular descriptors for protein research I.

For this reason there is a need to construct novel graphical representations of proteins and novel protein descriptors that can provide new information about the structure of proteins. Here a new set of protein descriptors based on computation of bilinear maps is presented. This novel approach to biomacromolecular design is relevant for QSPR studies on proteins. Protein bilinear indices are calculated from the kth power of nonstochastic and stochastic graph-theoretic electronic-contact .
