As a matter of common nomenclature in the petrochemical world (at least when you hear chemical engineers or chemists talking), carbon compounds widi single bonds are sometimes called saturates. (The carbon atoms are saturated with other atoms.) Those with multiple bonds are called unsaturates. 

So far nine arginine methyltransferases [46] and more than 20 lysine methyltransferases [11] have been identified in humans. Many of them show links to cancer. We discuss several of these subtypes below and an overview can be found in Tables 12.1 and 12.2. For lysine methyltransferases traditionally individual names have been used for the various subtypes. Lately, a common nomenclature for chromatin modifying enzymes has been proposed. For the human lysine methyltransferases the name KMTs should be used in analogy to (P)RMTs and eight groups (KMTl-8) with different subtypes suggested for some members [47]. But this nomenclature is not used consistently even throughout the recent literature so we provide both names if available in Table 12.2. 

When some of the chlorines are replaced by hydrogens, CFCs become HCFCs, the now more common nomenclature for those chlorofluorocarbons containing hydrogen. The numbering is the same. When more than one isomer is possible, the most symmetrically substituted compound has only a number letters a and b are added to designate less symmetrical isomers. 

Many elements can give rise to more than one elementary substance. These may be substances containing assemblages of the same mono- or poly-atomic unit but arranged differently in the solid state (as with tin), or they may be assemblages of different polyatomic units (as with carbon, which forms diamond, graphite and the fullerenes, and with sulfur and oxygen). These different forms of the element are referred to as allotropes. Their common nomenclature is essentially trivial, but attempts have been made to develop systematic nomenclatures, especially for crystalline materials. These attempts are not wholly satisfactory. 

Chemical name - the lUPAC or common nomenclature chemical title. 

The common nomenclature for di- or oligosaccharides specifies the order of monosaccharide units, the configuration at each anomeric carbon, and the carbon atoms involved in the glycosidic linkage (s). 

Although the name 111-1 -benzopyran is preferred by Chemical Abstracts, the more common nomenclature chrom-3-ene will be used throughout this review. 

A centrifugal pump is defined in the glossary at the end of this chapter as a machine in which a rotor in a casing acts on a liquid to give it a high velocity head that is in turn converted to pressure head by the time the liquid leaves the pump. Other common nomenclature relating to the construction and performance of centrifugal and related kinds of pumps also is in that table. 

In the common nomenclature for ethers, each of the R groups in R—O—R is named as a separate word, except when the groups are identical, in which case the prefix di or bis may be used (di is used for simple groups, bis for substituted groups) ... 

Hydrolysis and condensation reactions of silanes may be considered in the broad category of nucleophilic substitutions at silicon. The common nomenclature for these reactions is SN.V-Si, where A represents the kinetic order or molecularity, Si indicates that silicon is the reaction center, and SN indicates that the reaction is a nucleophilic substitution. Nucleophilic reactions at silicon have been reviewed thoroughly and have been the subject of fundamental studies by several laboratories over the last three decades [33]. The literature is not as voluminous as the literature on the corresponding reactions at carbon. A general mechanistic view of these reactions has, however, emerged. There are many parallels to carbon-centered reaction mechanisms. One distinction from carbon-centered reactions is clearly apparent. Silicon is able to form relatively stable higher coordinated (pentavalent) intermediates carbon is not [33].

The whiskers that are commonly added to silicon nitride to form composites are Si3N4 and SiC (common nomenclature is to add the suffix (w) to denote whiskers and this will be used where appropriate). Although other ceramic and metallic whiskers are available (e.g. BN, TaC, TiC, B4C and Fe), Si3N4 and SiC each have properties that make them prime candidates as reinforcements, not least of which is that they can sustain the high temperatures and reactivity of the sintering process without being degraded. 

Pharmaceutical clinical trials are often categorized into various phases, with any given trial being identified as belonging to one of them. These categories include Phase I, Phase II, and Phase III, and this common nomenclature was employed in Chapter 1 since it is likely that you were already familiar with it. However, there are alternate systems of categorization that are arguably more informative. A traditional description of phases is as follows ... 

Common nomenclature is for the Bunsen reaction section to be called Section 1, for the sulphuric acid section to be known as Section 2, and for the HI decomposition section to be designated as Section 3. 

Other structures such as a-(l,2-dithiol-3-ylidene)ketones (12) can be named according to common nomenclature because they do not possess the symmetry of the l,6,6a Slv-trithiapentalenes. However, even with such unsymmetrical systems, pentalene names may be useful, either to stress the fact that three heteroatoms are in line or to show the similarity with trithiapentalene derivatives, for instance, in the case of selenium analogs (13). 

A systematic method for naming alkanes (and other organic compounds) that is simple to use and minimizes memorization was developed by the International Union of Pure and Applied Chemistry and is called the IUPAC nomenclature. To make it easier for the chemists of that time to learn, it incorporated common nomenclature wherever possible.
