Egg white contains, apart from water (88%), mainly proteins (-11%), saccharides, mineral compounds and traces of lipids. The most abundant proteins (mostly glycoproteins) are ovoalbumin (54%), ovotransferin (13%), ovomocoid (11%), lysozyme (3.5%), other globulins (4%) and ovomucin (1.5 2%) some other proteins, e.g. ovoinhibitor, ovoflavoprotein, ovomicroglobulin and avidin [1], are present in traces (<1%). 

Dioctyl sebacate (DOS) with relative permittivity e of 3.9 and 2-nitrophenyl octyl ether (NPOE) with e = 23.9 are the traditionally used sensor membrane plasticizers. The choice of a plasticizer always depends on a sensor application. Thus, NPOE appears to be more beneficial for divalent ions due to its higher polarity, but for some cases its lipophilicity is insufficient. Furthermore, measurements with NPOE-plasticized sensors in undiluted blood are complicated by precipitation of charged species (mainly proteins) on the sensor surface, which leads to significant potential drifts. Although calcium selectivity against sodium and potassium for NPOE-based membranes is better by two orders of magnitude compared to DOS membranes, the latter are recommended for blood measurements as their lower polarity prevents protein deposition [92],...

Antibodies produced by this procedure were screened for their ability to react with the hapten to form the vinylogous amide 6, which has a convenient UV chromophore near 318nm, clear of the main protein absorption. Two antibodies selected in this way catalysed the expected aldol reaction of acetone with aldehyde 7 by way of the enamine 8 (Scheme 3) the remainder did not. These two effective aldolase mimics have been studied in some detail, and a crystal structure is available for (a Fab fragment of) one of them.126,281...

Macromolecular complexes of proteins and carbohydrate present in the ECM serve not only as adhesive keeping cells in their correct positions but also facilitate control of cell activity by signalling through membrane proteins such as the integrin family of receptors. Glycoproteins are mainly protein with covalently attached carbohydrate whereas proteoglycans are predominantly complex carbohydrates secured on a protein framework. 

Unlike the small molecule drugs (pharmaceuticals) described in Chapter 3, large molecule drugs (biopharmaceuticals) are mainly protein based. Another distinction is that these protein-based drugs are, in the main, similar to natural biological compounds found in the human body or they are fragments that mimic the active part of natural compounds. 

Biopharmaceuticals are mainly protein-based molecules, which are copies of natural biological compounds. The aim of these biopharmaceuticals is to modify or alter the undesirable biological responses in our body in the disease states. Biopharmaceuticals have molecular weights of tens of thousands of daltons, unlike the small molecule drugs of mostly less than 500 Da.

Integration of the electropherogram for an antibody to quantify main protein species percent light chain and heavy chain (%LC and %HC) and minor species such as percent non-main and percent high molecular weight species (%non-main species and %HMW) is shown in Figure 5. Corrected peak areas were used for quantification. The % corrected peak area is defined as ...

In gallstone patients, the nucleation of supersaturated bile requires either an excess of promoters, or a deficiency of inhibitors, of crystallisation (or both). For the past 20 years, attempts have been made to identify these pro- and antinucleating agents - but so far without consensus. Suffice to say that the promoters and inhibitors are mainly proteins and that mucous glycoprotein is particularly important - not only as a promoter of nucleation but also because it forms a gel on the surface of the gallbladder mucosa, which is believed to trap cholesterol crystals and contribute to the stasis within the gallbladder. Table 8.1 gives a list of potential promoters and inhibitors. 

Cellobiohydrolase I (CBH I, 1,4-jS-D-glucan-cellobiohydrolase, E.C. 3.2.1.91) is the main protein (ca. 60%) of the cellulase complex produced by T. reesei strains. CBH I hydrolyses crystalline cellulose, acid swollen cellulose and 4-methylumbelliferyl-cellodex-trins by cleaving off the terminal cellobiose unit from the non reducing end of the chain. It operates with retention of configuration in the reaction products 19,20. The abundance of this enzyme and its stability has facihtated its purification to homogeneity... 

Silk is produced from the spun threads from silkworms (the larvae of the moth Bombyx mori and related species). The main protein in silk, fibroin, consists of antiparallel pleated sheet structures arranged one on top of the other in numerous layers (1). Since the amino acid side chains in pleated sheets point either straight up or straight down (see p. 68), only compact side chains fit between the layers. In fact, more than 80% of fibroin consists of glycine, alanine, and serine, the three amino acids with the shortest side chains. A typical repetitive amino acid sequence is (Gly-Ala-Gly-Ala-Gly-Ser). The individual pleated sheet layers in fibroin are found to lie alternately 0.35 nm and 0.57 nm apart. In the first case, only glycine residues (R = H) are opposed to one another. The slightly greater distance of 0.57 nm results from repulsion forces between the side chains of alanine and serine residues (2). 

Linus Pauling, in 1954, received the Nobel Prize for his insights into the structure of materials, mainly proteins. Pauling showed that only certain conformations are preferred because of intermolecular and intramolecular hydrogen bonding. While we know much about the structures of natural macromolecules, there is still much to be discovered. 

TetraBDE did not competitively inhibit binding of T4 to sites in rat choroid plexus homogenates following in vitro or in vivo exposure (Sinjari et al. 1998). TTR is the only T4-binding protein synthesized by the choroid plexus and is the main protein involved in T4 transport from blood to brain in both rats and humans (Sinjari et al. 1998). 

The lactoglobulin fraction consists mainly of immunoglobulins (Ig), especially IgGj, with lesser amounts of IgG2, IgA and IgM (section 4.10). The lactalbumin fraction of bovine milk contains three main proteins, / -lactoglobulin (j8-lg), a-lactalbumin (a-la) and blood serum albumin (BSA), which represent approximately 50, 20 and 10% of total whey protein, respectively, and trace amounts of several other proteins, notably lactotrans-ferrin, serotransferrin and several enzymes. The whey proteins of sheep, goat...
