Schematic representation of the partial specific volume, V2, of some conjugated proteins (lipo-, glyco-, and nucleoproteins) consisting of two principal components (one protein and one nonprotein component) at varying weight percentages of these components. From [89D1]. For the volumes of the main components (protein, Upid, carbohydrate, nucleic acid) the average volumes, i], given in Table 5 were applied.

SR-BI is highly abundant in POS (Tserentsoodol et al., 2006a). Therefore it may be speculated that it plays a role in further uptake of carotenoid-enriched (lipo)proteins and their transport from the outer segment and then into deeper layers of the retina. 

Hyperlipoproteinemia, Type III, is a rare hereditary disease (also called familial dysbetalipoproteinemia) manifested by the occurrence of an uncommon P-lipo-protein form. Cholesterol and triglyceride contents in the patients may occasion-ally be 2-5 times superior to the norm.

To mimic nature in its irreversible monolipidation of proteins by N-myristoylation and S-prenylation, peptides are N-acylated with fatty acids or N-alkylated with linear or branched, saturated or unsaturated aliphatic chains as well as by incorporation of newly synthesized lipo-amino acids. 

Although the present finding that BLM formed from simple lipids alone can possess intrinsic low yb without the presence of protein layers, it in no sense invalidates the bimolecular leaflet model. Our study does suggest, however, that natural lipids such as lecithin when in a bilayer configuration could exist in natural membranes to give the results of low yt observed by earlier workers, which has been thought essential in the development of the concept of the bimolecular lipo-protein model based upon interfacial tension measurements. 

In clinical work many biological fluids have been submitted to paper electrophoretic separation. Serum and urine have been studied extensively and the results were reviewed in Volume I of this series (p. 238). Other fluids include cerebrospinal fluid (B12, B14, E6, K18), pleura] fluid (D4), gastric juice (H6), ascitic fluid (H9), synovial fluid (W3), proteins of the lens (F4, W9, W10), aqueous humor of the eye (W12, W24), edema liquid (W23), and pericardiac effusion (G2). Apart from the general separation of plasma proteins, work has been done on special protein groups, such as lipo- and glycoproteins, muco-proteins, hemoglobins (H19), coagulation factors (05), and on other components, such as amino acids. 

Alternatively, one strip (or, better, half of a strip cut lengthwise) is stained and used as a test for a second strip which is cut into appropriate lengths and eluted. There is, however, no certainty as to the limits of the zones of the protein fractions, for the factors involved in application and migration of protein samples are capable of destroying the parallelism of the two strips and of thus falsifying the results. Nevertheless, this method may be used and is even indispensable for the analysis of lipo-and glycoproteins with reference to the proteins themselves. 

The structure of the interfacial layers in food colloids can be quite complex as these are usually comprised of mixtures of a variety of surfactants and all are probably at least partly adsorbed at interfaces which even individually, can form complex adsorption layers. The layers can be viscoelastic. Phospholipids form multi-lamellar structures at the interface and proteins, such as casein, can adsorb in a variety of conformations [78]. Lecithins not only adsorb also at interfaces, but can affect the conformations of adsorbed casein. The situation in food emulsions can be complicated further by the additional presence of solid particles. For example, the fat droplets in homogenized milk are surrounded by a membrane that contains phospholipid, protein and semi-solid casein micelles [78,816], Similarly, the oil droplets in mayonnaise are partly coated with granular particles formed from the phospho and lipo-protein components of egg yolk [78]. Finally, the phospholipids can also interact with proteins and lecithins to form independent vesicles [78], thus creating an additional dispersed phase. 

Most important for the regulation of the membrane architecture are membrane potential, intracellular Ca2+ concentration, pH, changes in lipid composition due to the action of phospholipases and cell-cell coupling as well as the coupling of the membrane to the cytoskeleton and the extracellular matrix. Membrane architecture is additionally modulated by ions, lipo- and amphiphilic hormones, metabolites, drugs, lipid-binding peptide hormones, and amphitropic proteins [44].
