A simple approach to protein description consists of representing a protein by a sequence of properties of its constituent amino acids. Each amino acid is described by one ore more properties and therefore the total number of protein descriptors is given by the product of the number of amino acids in the protein and the number of selected amino acid properties. As this number of descriptors increases very fast with the size of proteins, this approach is usually applied to small- and medium-size peptides. Moreover, in QSAR studies that require uniform-length descriptors, it can be used only to describe a series of peptide analogues, vhich are peptide sequences with the same length. To enable QSAR studies of peptide sequences with different length, some method is required that is able to translate the peptide sequences into vectorial descriptors with the same number of variables. For example, ACC transforms were applied to compress information about principal properties of amino acids into peptide sequences with different length. 

Characterization of lectins as proteins is similar to the characterization of any protein descriptions may be found in published reviews [3,4,7].

Thus, the question about proteins description can be reformulated by finding a discreet language, able to codify the arbitrary form of a one-dimensional chain in a three- dimensional chain, analogously to the fact that proteins can appear in different stmctures, from primary (linear) to quaternary one (representing sets of linear chains deformed and compacted in three- dimensional/tertiary structures) (Putz, 2010b). 

The key for protein description relays in the properties of 3-dimen-sional simplex.

Since protein research is now at the apex of the third period of protein description marked by a precise knowledge of space parameters. Part I begins with a presentation of the structural characteristics of folded, globular proteins (Chapter 2). The hierarchy of protein organization as revealed by the different levels of structure is detailed. The most basic features, the structural invariants encountered in globular proteins are presented. The occurrence of a small number of topologies is examined from the double point of view of limitations in folding mechanisms and of protein evolution.
