A range of electrophoretic techniques use the capillary prindple capillary zone electrophoresis (CZE), capillary isotachophoresis (CITP), capillary gel electrophoresis (CGE), capillary isoelectric focusing (CIEF) and micellar electrokinetic capillary chromatography (MECC). Some of these techniques, particularly CZE and CGE, have already established themselves as important analytical tools others, notably MECC, may open new approaches in analytical biochemistry. Table 4-11 summarises the areas of application of the various techniques in what follows we shall focus on CZE, CGE and MECC. 

Metabolic Pathways of Biochemistry (table 7.1) has been maintained since 1998 by Karl Miller [1998] of The George Washington University s Biochemistry Department. It contains over 20 pathway diagrams with details on the structure and other... 

There are a variety of specialties within clinical biochemistry (Table I). Not every laboratory is equipped to carry out all possible biochemistry requests. Large departments may act as reference centres where less commonly asked for tests are [KMl ormed. For some tests which are needed in the diagnosis of rarediseases, there may be Just one or two laboratories in the country offering the service. 

In actual fact, the rumen processes are fairly unspecific and the diversity of fatty acids produced are absorbed and then grafted on to the more specific mammalian fatty acid biochemistry. Table 10.4 shows that the combination produces a quantitatively greater proportion of fatty acids with ethylenic bonds in unusual positions among the depot fat trans-18 1 isomers than among the cis-18 l isomers. This is even more obvious... 

The following table can only give a short overview of the most important or most used databases in Chemistiy and Biochemistry, It has no intention to be comprehensive or complete since the scenery of databases is changing very fast. 

The useful reviews of chemical and biological work on the tobacco alkaloids by Jackson,Roark, ( ) and Markwood issued in the United States have been referred to already and to these may be added that of Holman published in the United Kingdom, and the handbook of reference tables on the biochemistry of tobacco issued by Smirnov et al. in Russia. 

Despite the remarkable progress made, however, the trend shown in the table reveals a fact that cannot be interpreted favorably, at least to this author. In the third quarter of the 20th century, the structures of five different kinds of new luciferins have been determined, whereas, in the last quarter, only three structures, of which two are nearly identical, have been determined. None has been determined in the last decade of the century and thereafter, thus clearly indicating a declining trend, in contradiction to the steady advances in analytical techniques. The greatest cause for the decline seems to be the shift of research interest from chemistry and biochemistry into genetic biotechnology in the past 20 years.

The major objective of biochemistry is the complete understanding, at the molecular level, of all of the chemical processes associated with living cells. To achieve this objective, biochemists have sought to isolate the numerous molecules found in cells, determine their structures, and analyze how they function. Many techniques have been used for these purposes some of them are summarized in Table 1-1.

Table XI (346-390) lists a number of calcium-binding proteins and indicates very succinctly their role in biological systems. This table both illustrates the range of functions of calcium-binding proteins and serves to introduce those which appear subsequently in this chapter. The structures and functions of particularly important calcium-binding proteins such as calmodulin, parvalbumin, and troponin C are described in standard texts on biochemistry. The minimal Table XI entry for the particularly important calmodulins is amplified in the next paragraph. Table XI provides a sprinkling of references to enable readers to gain entry into the literature, for these and for most of the less-familiar species.

The nervous system contains an unusually diverse set of intermediate filaments (Table 8-2) with distinctive cellular distributions and developmental expression [21, 22]. Despite their molecular heterogeneity, all intermediate filaments appear as solid, rope-like fibers 8-12 nm in diameter. Neuronal intermediate filaments (NFs) can be hundreds of micrometers long and have characteristic sidearm projections, while filaments in glia or other nonneuronal cells are shorter and lack sidearms (Fig. 8-2). The existence of NFs was established long before much was known about their biochemistry or properties. As stable cytoskeletal structures, NFs were noted in early electron micrographs, and many traditional histological procedures that visualize neurons are based on a specific interaction of metal stains with NFs. 

Atoms that have the same atomic number, and hence are the same element, but have different masses are known as isotopes. Radioisotopes, or more correctly, radionuclides spontaneously and continuously emit characteristic types of radiation. They are particularly useful in analytical biochemistry, the unique nature of the radiation providing the basis for many specific and sensitive laboratory methods (Table 5.1).
