Section VI consists of discussions of eleven special topics nutrition, digestion, and absorption vitamins and minerals intracellular traffic and sorting of proteins glycoproteins the extracellular matrix muscle and the cy-toskeleton plasma proteins and immunoglobulins hemostasis and thrombosis red and white blood cells the metabolism of xenobiotics and the Human Genome Project. 

Polyanionic polymers can enter into biological functions by distribution throughout the host and they behave similar to proteins, glycoproteins and polynucleotides which modulate a number of biological responses related to the host defense mechanism. These are enhanced immune responses, and activation of the reticuloendothelial system (RES) macrophages.

In preparation for the next part of this course on the nervous system, we have to consider a very important site of action in and on the cell membrane. It is believed that most drugs act at a specific site called a receptor located within a target cell or in/on its membranes. Receptors are proteins, glycoproteins, lipoproteins, or nucleoproteins in their biochemical makeup. These receptors serve a natural purpose in that they form complexes with natural chemicals and these complexes trigger responses within a cell. A receptor, then, is a chemical entity which interacts with an... 

Although molecules with molecular mass greater than 5000 da, such as proteins, glycoproteins, and carbohydrates, can readily elicit a potent antibody formation, molecules such as drugs that have low molecular masses cannot stimulate an immunogenic response. These molecules, widely known as haptens, will bind with preformed antibodies but will not cause antibodies to be produced.

For several years, trifluoroacetic acid (TFA) has been used for the hydrolysis of proteins, glycoproteins, and glycosides (3,4,5,6), where the acid treatment is carried out under pressure at temperatures over 100°C.

Naturally occurring polysaccharides can occur either as individual carbohydrate molecules or in combination with other naturally occurring substances, such as proteins (glycoproteins) and lipids (glycolipids). In all cases the polysaccharide section may have linear or branched chain structures, which often contain the derivatives of both monosaccharides and aminosugars (Figure 1.20). 

Rabouille, Cortassa, and Aon[81 dried protein, glycoprotein, or polysaccharide containing brine solutions that resulted in dendritic-like fractal patterns. The fractal dimension, D = 1.79, was determined for the pattern afforded by an ovomucin-ovalbumin mixture (0.1 M NaCl). Similar D values were obtained for dried solutions of fetuin, ovalbumin, albumin, and starch the authors subsequently suggest that fractal patterning is characteristic of biological polymers. 

The complexity of the cestode tegument was discussed in Chapter 2. The brush border-plasma membrane subtending the tegument is a fluid-mosaic , consisting of proteins, glycoproteins and lipoproteins, embedded in a lipid bilayer (Fig. 2.3, p. 10). An array of membrane-bound proteins, many of which exhibit enzyme activity, is associated with the tegumental brush border plasma membrane. This important area has been comprehensively reviewed by Pappas (624).
