Chains terminology

Joel Sutherland of J.B. Hunt Logistics, Inc. has captured the essence of the discussion when he describes the difference between the term "logistics" and "supply chain." Sutherland was an active participant in the deliberations of the Council of Logistics Management and its efforts to build the lexicon of supply chain terminology. He points to three different common views of the supply chain. 

The general definition of a condensation reaction is a one that involves product formation by expulsion of water (or other small molecule) as a by-product. By this definition, activation and methylolation are also condensations. In more precise terms the chain-building process should be described as a condensation polymerization, however, in the jargon of the phenolics industry, the term condensation is usually reserved for the chain-building process. This terminology is not necessarily observed in the literature [88]. Many literature reports correctly refer to methylolation as a condensation reaction. The molecular weight development of the phenol alcohol adducts may also be classified as a step-polymerization. 

Peptide is the name assigned to short polymers of amino acids. Peptides are classified by the number of amino acid units in the chain. Each unit is called an amino acid residue, the word residue denoting what is left after the release of HgO when an amino acid forms a peptide link upon joining the peptide chain. Dipeptides have two amino acid residues, tripeptides have three, tetrapeptides four, and so on. After about 12 residues, this terminology becomes cumbersome, so peptide chains of more than 12 and less than about 20 amino acid residues are usually referred to as oligopeptides, and, when the chain exceeds several dozen amino acids in length, the term polypeptide is used. The distinctions in this terminology are not precise. 

There are basic terminology terms that aid in the description of chains. These arc (see Figure 3-27 [11]) the following ... 

Not all the problems that arise are clear-cut in fact, one problem may often mask another problem- or several minor problems may prove to be interdependent—providing a chain of cause and effect. As a result, different authorities may not always agree on the fundamental cause of a particular problem or even the precise chemistry involved. Terminology and problem definitions also may vary from country to country. 

When the substituent is an ionic chain [Fig. 13(b)] with the anion on the organic side, some of the lateral anions act as counter-ions during electrochemical oxidation. The cation of the salt is expelled from, or included in, the material during oxidation or reduction, respectively. These are self-compensating or self-doping (chemical or physical terminology, respectively) materials.76...

We start by learning how to name the alkyl substituents. These groups are named with the same terminology that we used for naming parent chains, but we add yl to the end to indicate that it is a snbstituent ... 

The authors refer to compound 9 as a monomer with tapered side chains and have only recently begun to use dendrimer terminology. Since the side chain meets the criteria for a G-l dendron, compound 9 is considered here. 

Hikosaka presented a chain sliding diffusion theory and formulated the topological nature in nucleation theory [14,15]. We will define chain sliding diffusion as self-diffusion of a polymer chain molecule along its chain axis in some anisotropic potential field as seen within a nucleus, a crystal or the interface between the crystalline and the isotropic phases . The terminology of diffusion derives from the effect of chain sliding diffusion, which could be successfully formulated as a diffusion coefficient in our kinetic theory.

Table 4.2 summarizes this basic classification and terminology of silicates. It is worth remembering that the term infinite refers here to an atomic scale of measurement, and does not imply that the chains extend to infinity in the mathematical sense of the word The terminology surrounding the silicates and clay minerals, in common with other mineralogical terms, has never been fully systematized, and so the names given are often ill-defined, or not unique to a...
