Nomenclature and Abbreviations

A complete table of abbreviations used in this text is in the Appendix, but a few are so common they need to be learned early. 

Brpnsted base, accepts a proton from a Brpnsted acid A partial positive charge A partial negative charge 

Electrophile or Lewis acid, an electron pair acceptor Electron-releasing group Electron-withdrawing group Ethyl, CH3CH2 

Brpnsted acid, donates a proton to a Brpnsted base Leaving group, departs with its bonding electron pair Metal 

Nucleophile or Lewis base, an electron pair donor Phenyl group, C Hj, a monosubstituted benzene 

B droplet width, or the smaller E, dimensionless breakup time. 

Cl screw center-to-center distance V free volume of the extrader 

V average flow velocity DCPO dicumyl peroxide 

Zl2 thermodynamic binary interaction EME elastic melt extruder 

Tld Tim viscosity of dispersed and matrix ICRR intermeshing counter-rotating TSE

Unfortunately, definitions, nomenclature, and abbreviations used for performance criteria are sometimes confusing (Frank and Todeschini 1994 Kramer 1998). For instance in the abbreviations MSEC, PRESS, RMSEP, SEC, SEE, SEP, E means error or estimate, R means residual or root, and S means squared or standard or sum. To make it not too complicated, at least in these examples, C is always calibration, M is mean, and P is prediction.

Alkoxysilanes have the general formula Si(OR)4. In most cases the organic R group is methyl or ethyl. Nomenclature and abbreviations are as follows ... 

Oxysterols are defined as oxygenated derivatives of cholest-5-en-3(3-ol (cholesterol) (Figure 18.1) or precursors of CHOL that may be formed directly by autoxidation or by the action of a specific monooxygenase, or that may be secondary to enzymatic or nonenzymatic lipid peroxidation (Guardiola et al., 1996 Schroepfer, 2000 Bjorkhem and Diczfalusy, 2002). These OS may be formed in the human body by endogenous free-radical attack on CHOL or by enzymatic processes, mainly in the biosynthesis of bile acids and steroid hormones. In addition, OS may be formed exogenously by autoxidation of CHOL in foods. The nomenclature and abbreviations of OS are presented in Table 18.1. It should be emphasized at this point that the OS that occur in...

When requesting permission, please identify all the figures you wish to reproduce. Allow four weeks for your request to be processed. We recommend that you use the nomenclature and abbreviation scheme that we developed for this book. This scheme has been developed on a systematic basis (see below) and is now widely recognized. 

Figure 2.3 MS/MS fragmentation pattern of some glycerophospholipids (see also Table 2.1). Nomenclature and abbreviations are those recommended by Fahy. (Fahy, E. et al., 2005, A Comprehensive Classification System for Lipids, /. Lipid Res. 46 839-61.)...

The reader should become acquainted with the nomenclature and abbreviations of the glossary which follows to derive maximum benefit from quick scans of the tabular material. 

We possess nowadays a vastly improved idea of the occurrence and chemical changes of the E vitamins, thanks to intensive application and expansion of thin-layer chromatographic methods. Pennock et al. [104, 105] have investigated the naturally occurring tocopherols and tocotrienols (saturated or unsaturated side-chains, respectively) and proposed the following nomenclature and abbreviations, on the basis of their results ... 

We have chosen the first lUPAC suggestion (in [90]) for the consistent nomenclature and abbreviations of some of these quinones, the list of which is continuously growing ...
