The authors would like to express their thanks to NSERC for funding this work and for scholarship support (JS). Thanks are also extended to the UBC mechanical, electronic, and glassblowing services, whose efforts have been crucial in the development of these experiments. The determination of the surface crystallography by electron-backscattered diffraction (EBSD) was performed by Prof. C. Sinclair, and creation of the stepped surface was accomplished by Dr. M. Beaudoin.

The structures and abbreviations for the 20 amino acids commonly found in proteins are shown in Figure 4.3. All the amino acids except proline have both free a-amino and free a-carboxyl groups (Figure 4.1). There are several ways to classify the common amino acids. The most useful of these classifications is based on the polarity of the side chains. Thus, the structures shown in Figure 4.3 are grouped into the following categories (I) nonpolar or hydrophobic...

In this section, the treatment of complexes of different nuclearities is based on the ligand systems involved, but this is occasionally arbitrary as two different ligands may be present. The structures and abbreviations of ligands referred to in this section are shown in Figures 2 and 3 and 16-19. 

Another family of coupling reagents is used frequently with the Fmoc method. These are related to benzotriazole and 7-azabenzotriazole but also incorporate amidinium or phosponium groups. The structures and abbreviations of these reagents are given in Scheme 13.54.

Trimethoxysilyl)propyloctadecyldimethylammonium chloride (SiQAC) was obtained from Dow Coming Corporation, Midland, MI, as a 40% solution in methanol. A suitable aliquot of this solution was rotary-evaporated to remove most of the methanol and then diluted to 10 ml with an appropriate solvent. An infrared spectrum was recorded immediately after this procedure to obtain the initial methanol concentration. It was observed that complete evaporation of the methanol to solid SiQAC results in hydrolysis of the methoxy groups and condensation of the silanol groups to form siloxane bonds. Scheme 1 shows the structures and abbreviations of all the compounds used in this investigation.

Enzymes are made from just 20 a-amino acid building blocks (structures and abbreviations are shown in Table 5.1). Each amino acid has a unique side chain, or residue, which can be polar, aliphatic, aromatic, acidic, or basic. The amide bonds (peptide bonds) make up the enzyme s backbone, and the residues determine the ultimate structure and catalytic activity of the enzyme. When the sequence of amino acids (the primary structure) for an enzyme is assembled in vivo, it folds... 

In particular, the six-membered diamine chelate complex, A-[Co(tn)3]3+ (tn(tri-methylendiamine), the strained five-membered diamine chelate complex A(888)-[Co( -cptn)3]3 + (cptn = trans- 1,2-cyclopentanediamine), and the seven-membered diamine chelate complex A-[Co(tmd)3]3+ (tmd= 1,4-diaminobutane) display a major negative CD in the spin-allowed lrTi<— Aj transition, where the diamine ligand structures and abbreviations are shown in Figure 5.27.

When this sudoku puzzle is assigned, some training of students is recommended. One possibility is, at the onset of the discussion of amino acids, to hand out the puzzle and to use it as one of the visual aids to point out the basics of amino acids. The instructor can show the correlation of the name, structure, and abbreviations and then follow up with a demonstration of the method and thought process used to solve the puzzle. For instance, as a class, one may complete all instances of lysine in the puzzle. Students who are unfamiliar with this type of puzzle would learn the strategy necessary. All students would better comprehend the necessity of identifying which structures, names, and abbreviations are correlated with each other.

The structures and abbreviations for the most commonly used bulky 2,6- and 2,4,6-substituted aromatic thiols are shown in Fig. 1. These aromatic thiols have the advantage over those with aliphatic groups that the tendency for C—S bond cleavage is virtually eliminated, which in turn lessens the probability of generating unreactive sulfide-bridged polymers.

The structures and abbreviations used for designating the calix[4]arenes are shown in (5). These calix[4]arenes, have both a wide (upper) and a narrow (lower) rim that can be chemically modified to produce complexants that are selective for particular metal ions. In the simple calixarene framework the wide rim has hydrocarbon functionalities, and the narrow rim phenolic groups. Calixarenes are conformationally mobile, and the extreme structures for the calix[4]arenes have been termed the cone, partial cone, 1,3-alternate, and 1,2-alternate conformations (6). Because of the conical geometry of the calix[4]arene structure, the cavity size of the wide rim is larger than that of the narrow rim.
