Protein albumin

Two classes of antioxidants are known the low-molecular weight compounds (tocopherols, ascorbate, -carotene, glutathione, uric acid and etc.) and the proteins (albumin, transferrin, caeruloplasmin, ferritin, etc.) including antioxidant enzymes (e.g. superoxide dismutase, catalase, glutathione peroxidase). [Pg.354]

Water-soluble compounds are naturally easily transported in the blood. Non-soluble compounds are usually transported bound to plasma proteins (albumins). This binding is reversible in most cases but may vary remarkably. The degree of protein binding may vary between 50% and 99%. The proportion of the free (unbound) compound in the circulation is the amount of the compound that can reach the tissues and thus the target organs. Very lipid-... [Pg.290]

Table 50-2 summarizes the functions of many of the plasma proteins. The remainder of the material in this chapter presents basic information regarding selected plasma proteins albumin, haptoglobin, transferrin, ceruloplasmin, aj-antitrypsin, aj i roglobulin, the immunoglobulins, and the complement system. The lipoproteins are discussed in Chapter 25. [Pg.583]

Albumin (69 kDa) is the major protein of human plasma (3.4-4.7 g/dL) and makes up approximately 60% of the total plasma protein. About 40% of albumin is present in the plasma, and the other 60% is present in the extracellular space. The liver produces about 12 g of albumin per day, representing about 25% of total hepatic protein synthesis and half its secreted protein. Albumin is initially synthesized as a preproprotein. Its signal peptide is removed as it passes into the cisternae of the rough endoplasmic reticulum, and a hexapeptide at the resulting amino terminal is subsequently cleaved off farther along the secretory pathway. The synthesis of albumin is depressed in a variety of diseases, particularly those of the liver. The plasma of patients with liver disease often shows a decrease in the ratio of albumin to globulins (decreased albumin-globuhn ratio). The synthesis of albumin decreases rela-... [Pg.583]

Polyphenols are not found free in the blood but are bound to plasma proteins. Albumin is the primary protein responsible for the bindings of several polyphenols and their metabolites (i.e., quercetin, kempferol, isorhamnetin), but no data are available for anthocyanins. However it is probable that anthocyanin derivatives also bind to albumin and the degree of that binding may affect the clearance rate and the delivery to tissues of these compounds as well. [Pg.168]

The Ru(IV)/Ru(III) redox potential is 0.78 V, so that Ru(III) or even Ru(II) species may be present in vivo. Indeed, the related Ru(III) complex 32 is also active (171), and the pendant arms in these octahedral polyaminocarboxylate complexes increase the rate of substitution reactions. Complex 32 binds rapidly to the blood proteins albumin and transferrin (172), and the ruthenium ion appears to remain in the... [Pg.212]

Contrary to popular belief, ceruloplasmin5, the principal copper-containing protein in plasma, ceruloplasmin, is not involved in copper transport. This is clearly underlined by the clinical observation that patients with aceruloplasminaemia (i.e. lacking ceruloplasmin in their blood) have perfectly normal copper metabolism and homeostasis. Copper is transported in plasma mostly by serum albumin with smaller amounts bound to low-molecular weight ligands like histidine. Likewise zinc is mostly transported in plasma bound to proteins (albumin and ot2-macroglobulin). [Pg.148]

Unfortunately, the low aqueous solubility of the DCL components precluded templating studies with the intended target microtubulin. As proof of principle, the proteins albumin and subtilisin were substituted as organic solvent tolerant alternatives. Starting from the homodimeric compounds 45 and 48, the amount of heterodimer 51 formed was shown to be influenced by the presence of the proteins. [Pg.62]

Similar to the approaches followed with cyanine dyes (Chapter 3.1.3), attempts to enhance the selectivity of photosensitizers by conjugating to target-specific vehicles have been described [98]. The approaches included conjugates with antibodies [99, 100], antibody fragments [58, 101], peptides [102], the serum proteins albumin and transferrin [103,104] and estradiol [105]. [Pg.18]

It has been reported that in normal individuals who eat a standard breakfast there is no significant change in blood urea nitrogen, carbon dioxide content, chloride, sodium, potassium, calcium, phosphorus, total protein, albumin, creatinine, uric acid, cholesterol, and cholesterol esters (A4). It should be emphasized again that the effects of fasting are quite different in normal, healthy persons than in sick people. [Pg.19]

The parameters Vp, Vg and are the plasma and extracellular fluid volumes and the extravascular to intravascular protein (albumin) ratio, respectively. Their values in human, as an example, are 0.0436 and 0.151 L/kg, respectively, with a ratio of 1.4. [Pg.211]

Calcium is present in three forms e.g., as free calcium ion, bound to plasma protein albumin and in diffusable complexes. The endocrine system, through parathyroid hormone and calcitonin, helps in keeping the concentration of ionized plasma calcium in normal level. Decrease in plasma levels of ionized calcium leads to increased parathyroid hormone secretion. Parathyroid hormone tends to increase plasma calcium level by increasing bone resorption, increasing intestinal absorption and increasing reabsorption of calcium in kidney. Vitamin D acts by stimulating... [Pg.390]

Total protein, albumin, urea (standard methods) and middle molecules (MM) were determined in citrated plasma [6]. The trypsin-like activity (TLA) of plasma was measured using the chromogenic peptide substrate (Z-glycyl-glycyl-L-arginine-4-nitroanilide) [7]. Evaluation of anti-enzymatic potential in plasma was based on concentrations of the main protease inhibitors -proteinase inhibitor (ttj-PI) and aj-macroglobulin (a -M). Student s t-test was used for statistical analysis. [Pg.282]

Beissinger and Leonard71 modeled the competitive adsorption of two proteins, albumin (A) and IgG (G), permitting each protein to occupy part of the surface in two different states, and also allowing for desorption of each protein from each of its two allowed states. The model uses 12 adjustable parameters, making it difficult to apply for predictive purposes. [Pg.40]
