Figure S.2 Schematic and topological diagrams of an up-and-down fi barrel. The eight p strands are all antiparallel to each other and are connected by hairpin loops. Beta strands that are adjacent in the amino acid sequence are also adjacent in the three-dimensional structure of up-and-down barrels.

Figure 9.8 Schematic diagram of the three-dimensional structure of the Antennapedia homeodomain. The structure is built up from three a helices connected by short loops. Helices 2 and 3 form a helix-turn-hellx motif (blue and red) similar to those in procaryotic DNA-binding proteins. (Adapted from Y.Q. Qian et al.. Cell 59 573-580, 1989.)...

Crystalline solids display a very regular ordering of the particles in a three-dimensional structure called the crystal lattice. In this crystal lattice there are repeating units called unit cells. See your textbook for diagrams of unit cells. 

Fig. 2.8 Cleavage in the amphiboles. (A) Schematic representation of the characteristic stacked amphibole I-beams in the three-dimensional structure. A tetrahedral portion of an I-beam is labeled "silica ribbon." The octahedral portion is labeled "cation layer" and represented by solid circles. One of the possible cleavage directions (110) along planes of structural weakness is indicated by the line A-A stepped around the I-beams in the lower part of the diagram. (B) Cross section of the stacked I-beams with the directions of easy cleavage indicated. There is a lower density of bonds between I-beams in the crystallographic directions (110) and (110). These directions, parallel to the c axis and the length of the chains, are the planes of cleavage. The minimum thickness of a rhombic fragment produced through cleavage is 0.84 nm.

Much of what we need to know abont the thermodynamics of composites has been described in the previous sections. For example, if the composite matrix is composed of a metal, ceramic, or polymer, its phase stability behavior will be dictated by the free energy considerations of the preceding sections. Unary, binary, ternary, and even higher-order phase diagrams can be employed as appropriate to describe the phase behavior of both the reinforcement or matrix component of the composite system. At this level of discussion on composites, there is really only one topic that needs some further elaboration a thermodynamic description of the interphase. As we did back in Chapter 1, we will reserve the term interphase for a phase consisting of three-dimensional structure (e.g., with a characteristic thickness) and will use the term interface for a two-dimensional surface. Once this topic has been addressed, we will briefly describe how composite phase diagrams differ from those of the metal, ceramic, and polymer constituents that we have studied so far.

The three-dimensional structure of rat liver metallothionein containing five Cd2+ and two Zn2+ ions is shown in the accompanying stereoscopic diagram.1 The 61 alpha carbons, the beta carbon and sulfur atoms (green) of cysteine residues and the bound metal ions are indicated. 

Figure 29-4 Structure of 23S-28S ribosomal RNAs. (A) The three-dimensional structure of RNA from the 50S subunit of ribosomes of Halocirculci marismortui. Both the 5S RNA and the six structural domains of the 23S RNA are labeled. Also shown is the backbone structure of protein LI. From Ban et al.17 Courtesy of Thomas A. Steitz. (B) The corresponding structure of the 23S RNA from Thermus thermophilus. Courtesy of Yusupov et al.33a (C) Simplified drawing of the secondary structure of E. coli 23S RNA showing the six domains. The peptidyltransferase loop (see also Fig. 29-14) is labeled. This diagram is customarily presented in two halves, which are here connected by dashed lines. Stem-loop 1, which contains both residues 1 and 2000, is often shown in both halves but here only once. From Merryman et al.78 Similar diagrams for Haloarcula marismortui17 and for the mouse79 reveal a largely conserved structure with nearly identical active sites.

Even a molecule with as defined a three-dimensional structure as the fullerene C60 is topologically planar (Fig. 7-4). This type of representation is known as a Schlegel diagram.
