Porphyrias can also be classified as acute or cutaneous on the basis of their clinical features prostate cancer biopsy order discount alfuzosin line. Thus prostate cancer tests order alfuzosin 10 mg with mastercard, taking drugs that cause induction of cytochrome P450 (so-called microsomal inducers) can precipitate attacks of porphyria man health 365 order alfuzosin from india. The major findings in the six principal types of porphyria are listed in Table 32­2 mens health 8 pack abs generic alfuzosin 10 mg on-line. When hemoglobin is destroyed in the body, globin is degraded to its constituent amino acids, which are reused, and the iron of heme enters the iron pool, also for reuse. The catabolism of heme from all of the heme proteins appears to be carried out in the microsomal fractions of cells by a complex enzyme system called heme oxygenase. By the time the heme derived from heme proteins reaches the oxygenase system, the iron has usually been oxidized to the ferric form, constituting hemin. With the further addition of oxygen, ferric ion is released, carbon monoxide is produced, and an equimolar quantity of biliverdin results from the splitting of the tetrapyrrole ring. The daily bilirubin formation in human adults is approximately 250­350 mg, deriving mainly from hemoglobin but also from ineffective erythropoiesis and from various other heme proteins such as cytochrome P450. The chemical conversion of heme to bilirubin by reticuloendothelial cells can be observed in vivo as the purple color of the heme in a hematoma is slowly converted to the yellow pigment of bilirubin. Bilirubin monoglucuronide is an intermediate and is subsequently converted to the diglucuronide (Figures 32­13 and 32­14). Most of the bilirubin excreted in the bile of mammals is in the form of bilirubin diglucuronide. In 100 mL of plasma, approximately 25 mg of bilirubin can be tightly bound to albumin at its highaffinity site. A number of compounds such as antibiotics and other drugs compete with bilirubin for the high-affinity binding site on albumin. This facilitated transport system has a very large capacity, so that even under pathologic conditions the system does not appear to be rate-limiting in the metabolism of bilirubin. Ligandin (a family of glutathione S-transferases) and protein Y are the involved proteins. Bilirubin Is Secreted Into Bile Secretion of conjugated bilirubin into the bile occurs by an active transport mechanism, which is probably ratelimiting for the entire process of hepatic bilirubin metabolism. It is located in the plasma membrane of the bile canalicular membrane and handles a number of organic anions. The hepatic transport of conjugated bilirubin into the bile is inducible by those same drugs that are capable of inducing the conjugation of bilirubin. Thus, the conjugation and excretion systems for bilirubin behave as a coordinated functional unit. Figure 32­15 summarizes the three major processes involved in the transfer of bilirubin from blood to bile. Sites that are affected in a number of conditions causing jaundice (see below) are also indicated. Hepatocytes convert bilirubin to a polar form, which is readily excreted in the bile, by adding glucuronic acid molecules to it. This process is called conjugation and can employ polar molecules other than glucuronic acid (eg, sulfate). Glucuronic acid is attached via ester linkage to the two propionic acid groups of bilirubin to form an acylglucuronide. In the terminal ileum and large intestine, a small fraction of the urobilinogens is reabsorbed and reexcreted through the liver to constitute the enterohepatic urobilinogen cycle. Under abnormal conditions, particularly when excessive bile pigment is formed or liver disease interferes with this intrahepatic cycle, urobilinogen may also be excreted in the urine. Normally, most of the colorless urobilinogens formed in the colon by the fecal flora are oxidized there to urobilins (colored compounds) and are excreted in the feces (Figure 32­16). Diagrammatic representation of the three major processes (uptake, conjugation, and secretion) involved in the transfer of bilirubin from blood to bile. Certain proteins of hepatocytes, such as ligandin (a family of glutathione S-transferase) and Y protein, bind intracellular bilirubin and may prevent its efflux into the blood stream. Hyperbilirubinemia may be due to the production of more bilirubin than the normal liver can excrete, or it may result from the failure of a damaged liver to excrete bilirubin produced in normal amounts.

After esterification with CoA prostate kegels purchase discount alfuzosin, propionyl-CoA is carboxylated to D-methylmalonyl-CoA prostate 13 buy alfuzosin master card, catalyzed by propionyl-CoA carbox165 Pyruvate & Phosphoenolpyruvate Reversal of the reaction catalyzed by pyruvate kinase in glycolysis involves two endothermic reactions wikibooks prostate radiation oncology purchase alfuzosin 10mg with amex. Entry points of glucogenic amino acids after transamination are indicated by arrows extended from circles (see also Figure 17­4) mens health uk buy alfuzosin 10 mg low price. Arrows with wavy shafts signify allosteric effects; dash-shafted arrows, covalent modification by reversible phosphorylation. Methylmalonyl-CoA racemase catalyzes the conversion of d-methylmalonyl-CoA to l-methylmalonyl-CoA, which then undergoes isomerization to succinyl-CoA catalyzed by methylmalonylCoA mutase. Methylmalonyl-CoA mutase is a vitamin B12-dependent enzyme, and in deficiency methylmalonic acid is excreted in the urine (methylmalonicaciduria). Glycerol is released from adipose tissue as a result of lipolysis of lipoprotein triacylglycerol in the fed state; it may be used for reesterification of free fatty acids to triacylglycerol in adipose tissue or liver, or may be a substrate for gluconeogenesis in the liver. In the fasting state glycerol released from lipolysis of adipose tissue triacylglycerol is used solely as a substrate for gluconeogenesis in the liver and kidneys. The enzymes involved in the utilization of glucose (ie, those of glycolysis and lipogenesis) become more active when there is a superfluity of glucose, and under these conditions the enzymes of gluconeogenesis have low activity. Insulin, secreted in response to increased blood glucose, enhances the synthesis of the key enzymes in glycolysis. They also affect the concentration of fructose 2,6bisphosphate and therefore glycolysis and gluconeogenesis, as described below. Three mechanisms are responsible for regulating the activity of enzymes concerned in carbohydrate metabolism: (1) changes in the rate of enzyme synthesis, (2) covalent modification by reversible phosphorylation, and (3) allosteric effects. Allosteric Modification Is Instantaneous In gluconeogenesis, pyruvate carboxylase, which catalyzes the synthesis of oxaloacetate from pyruvate, requires acetyl-CoA as an allosteric activator. The addition of acetyl-CoA results in a change in the tertiary structure of the protein, lowering the Km for bicarbonate. This means that as acetyl-CoA is formed from pyruvate, it automatically ensures the provision of oxaloacetate and, therefore, its further oxidation in the citric acid cycle, by activating pyruvate carboxylase. The activation of pyruvate carboxylase and the reciprocal inhibition of pyruvate dehydrogenase by acetyl-CoA derived from the oxidation of fatty acids explain the action of fatty acid oxidation in sparing the oxidation of pyruvate and in stimulating gluconeogenesis. The enzymes involved catalyze nonequilibrium (physiologically irreversible) reactions. Insulin alters the metabolic fate of pyruvate as the tissue changes from carbohydrate oxidation (glycolysis) to gluconeogenesis during the transition from the fed to fasting state (see Figure 20­1). Phosphofructokinase (phosphofructokinase-1) occupies a key position in regulating glycolysis and is also subject to feedback control. A consequence of the inhibition of phosphofructokinase-1 is an accumulation of glucose 6-phosphate, which in turn inhibits further uptake of glucose in extrahepatic tissues by inhibition of µ hexokinase. Fructose 2,6-Bisphosphate Plays a Unique Role in the Regulation of Glycolysis & Gluconeogenesis in Liver the most potent positive allosteric activator of phosphofructokinase-1 and inhibitor of fructose 1,6-bisphosphatase in liver is fructose 2,6-bisphosphate. It inhibits fructose 1,6-bisphosphatase by increasing the Km for fructose 1,6-bisphosphate. Its concentration is under both substrate (allosteric) and hormonal control (covalent modification) (Figure 20­3). The same enzyme protein is also responsible for its breakdown, since it has fructose 2,6-bisphosphatase activity. This bifunctional enzyme is under the allosteric control of fructose 6-phosphate, which stimulates the kinase and inhibits the phosphatase. The activity of phosphofructokinase-1 is thus regulated in response to the energy status of the cell to control the quantity of carbohydrate undergoing glycolysis prior to its entry into the citric acid cycle. Hence, gluconeogenesis is stimulated by a decrease in the concentration of fructose 2,6-bisphosphate, which inactivates phosphofructokinase-1 and relieves the inhibition of fructose 1,6-bisphosphatase. Substrate (Futile) Cycles Allow Fine Tuning & Rapid Response the control points in glycolysis and glycogen metabolism involve a cycle of phosphorylation and dephosphorylation catalyzed by glucokinase and glucose 6-phosphatase; phosGlycogen glucose phofructokinase-1 and fructose 1,6-bisphosphatase; pyruvate kinase, pyruvate carboxylase, and phosphoenolpyruvate carboxykinase; and glycogen synthase and phosphorylase. While this is so, in muscle both phosphofructokinase and fructose 1,6-bisphosphatase have some activity at all times, so that there is indeed some measure of (wasteful) substrate cycling. This permits the very rapid increase in the rate of glycolysis necessary for muscle contraction. At rest the rate of phosphofructokinase activity is some 10-fold higher than that of fructose 1,6-bisphosphatase; in anticipation of muscle contraction, the activity of both enzymes increases, fructose 1,6-bisphosphatase ten times more than phosphofructokinase, maintaining the same net rate of glycolysis. A sudden decrease in blood glucose (eg, in response to insulin overdose) causes convulsions, because of the dependence of the brain on a supply of glucose.
