Transport iron

For iron transport and control problems at pressures of up to 1,500 or possibly as high as 1,800 psig, copolymers such as AA/VS or AA/NI-AS-LS, or terpolymers such as AA/SA/SSS should be used. [Pg.457]

Where iron transport takes place, accurate monitoring over a period and under different load conditions is required before filters, polishers, and other components can be properly sized. [Pg.298]

Transferrin binds iron, transporting it to sites where it is required. Ferritin provides an intracellular store of iron. Iron deficiency anemia is a very prevalent disorder. Hereditary hemochromatosis has been shown to be due to mutations in HFE, a gene encoding the protein HFE, which appeats to play an important role in absorption of iron. [Pg.597]

In smaller plants, the iron transported through to the boiler is essentially hematite, but in larger plants, this oxide is subject to thermal [Pg.297]

Figure 50-4. Absorption of iron. is converted to Fe + by ferric reductase, and Fe " is transported into the enterocyte by the apicai membrane iron transporter DMTl. Fieme is transported into the enterocyte by a separate heme transporter (HT), and heme oxidase (FiO) reieases Fe from the heme. Some of the intraceiiuiar Fe + is converted to Fe + and bound by ferritin. The remainder binds to the basoiaterai Fe + transporter (FP) and is transported into the biood-stream, aided by hephaestin (FiP). in piasma, Fe + is bound to the iron transport protein transferrin (TF).

Problem-specific polymers include terpolymers, used for iron dispersion, iron transport, and silica control. [Pg.389]

Other non-haem proteins, distinct from the above iron-sulfur proteins are involved in the roles of iron transport and storage. Iron is absorbed as Fe" in the human duodenum and passes into the blood as the Fe protein, transferrin, The Fe is in a distorted octahedral environment consisting of 1 x N, 3x0 and a chelating carbonate ion which [Pg.1103]

Dispersants are often also specified, depending on the level of iron and BW sludge present. Iron transport polymers such as acrylic acid/sodium 3-allyloxy-2-hydropropane (AA/COPS) and phos-phinocarboxylic acid (PCA) usually are the most suitable. [Pg.607]

Oxygenation treatment also reduces the risk of erosion-corrosion problems and limits iron transport to other parts of the boiler system where fouling could take place. [Pg.168]

Iron is another vital nutrient in the development of functioning erythrocytes it is essential for the formation of hemoglobin. Lack of iron leads to a decrease in hemoglobin synthesis and ultimately red blood cells. Normal homeostasis of iron transport and metabolism is depicted in Fig. 63-2.7 Approximately 1 to 2 mg of iron is absorbed through the duodenum each day, and the same amount is lost via blood loss, desquamation of mucosal cells, or menstruation. [Pg.977]

The mutant L37 cbrA21 is affected as regards to its iron uptake pathway mediated by the siderophore achromobactin. Because this mutation results in derepression of the chrysobactin mediated iron transport pathway, the mutant is probably less susceptible to iron deprivation than wild-type cells are, when entering the host. This results in a delay in Pels production thus leading to delayed symptoms, as reported by Sauvage and Expert (1994). [Pg.879]

A good condensate control program, using the correct mix of different distribution ratio (DR) neutralizing amines, will minimize corrosion and limit iron transport. A standard control method is often [Pg.662]

The po.ssible role of a chelate reductase for iron uptake from microbial siderophores has been examined for several plant species (30,47). With certain microbial siderophores such as rhizoferrin and rhodotorulic acid, the reductase may easily cleave iron from the siderophore to allow subsequent uptake by the ferrous iron transporter. However, with the hydroxamate siderophore, ferrioxamine B, which is produced by actinomycetes and u.sed by diverse bacteria and fungi, it has been shown that the iron stress-regulated reductase is not capable [Pg.231]
