Phosphate transport by insulin
WebTraductions en contexte de "precipitation of zinc-phosphate" en anglais-français avec Reverso Context : Mixing of Ultratard with phosphate buffered insulin preparations is not recommended due to the risk of precipitation of zinc-phosphate, leading to an unpredictable timing of such insulin mixtures. WebMay 8, 2024 · Other excipients include dibasic sodium phosphate and monobasic sodium phosphate monohydrate. 5 Like other commercially available ... There are limited data demonstrating the extent of denaturation that occurs in the transport of insulin products; however, Ward et al 12 showed that transportation via pneumatic tube did not alter the …
Phosphate transport by insulin
Did you know?
WebThe insulin transduction pathway is a biochemical pathway by which insulin increases the uptake of glucose into fat and muscle cells and reduces the synthesis of glucose in the liver and hence is involved in maintaining glucose homeostasis. This pathway is also influenced by fed versus fasting states, stress levels, and a variety of other hormones. WebOct 9, 1998 · We suggest the hypothesis that insulin resistance is dependent on whether glucose is entering through GLUT1 or GLUT4 and on the two functional compartments of glucose 6-phosphate formation within the cell. Glucose entering the muscle cell through GLUT4 and phosphorylated by hexokinase II is mainly directed to glycogen synthesis and …
WebAbbreviations: IR = insulin receptor; GSK3 = glycogen synthase kinase-3; PKA = CAMP-dependent kinase; PPl = protein phosphatase-1; GS = glycogen synthase; GP = glycogen …
WebThese data demonstrate that insulin-stimulated rates of mitochondrial ATP synthesis are reduced in IR offspring of parents with type 2 diabetes. Furthermore, these IR offspring … Web1. Insulin facilitates entry of glucose into muscle, adipose and several other tissues. The only mechanism by which cells can take up glucose is by facilitated diffusion through a family of hexose transporters.In many tissues - muscle being a prime example - the major transporter used for uptake of glucose (called GLUT4) is made available in the plasma …
WebMar 28, 2024 · Normally, pancreatic beta cells regulate serum glucose levels through tight control of insulin secretion. Glucose first enters the beta cell via a GLUT2 transporter and is converted to glucose-6-phosphate via glucokinase. Glucose-6-phosphate acts as the initial substrate for the complex metabolic and biochemical processes that produce ATP.
WebAug 16, 2005 · The parallel reductions in insulin-stimulated rates of muscle glucose metabolism, which can mostly be attributed to reduced insulin-stimulated glucose transport activity [ 27 ], and reduced insulin-stimulated phosphate transport activity suggests that a common insulin-signaling defect may be responsible for both of these abnormalities [ 28 ]. chips first airedWebJun 1, 1992 · The effect of glucose on phosphate uptake was determined by the addition of varying concentrations of glucose (between 0 and 32 mmol/L) to the extravesicular … chips fingerWebWhen these mutations were introduced into a strain dependent on a single system, the pst system, for inorganic phosphate (P(i)) transport, profound changes in P(i) transport were observed. The phoT mutations led to a complete P(i) (-) phenotype in this background, and no activity of the pst system could be detected. ... When glucose-6-phosphate ... chips fitWebDec 5, 2013 · Here, we have investigated the role of inorganic phosphate (P i) transport in mitochondria of rat clonal β-cells.In α-toxin-permeabilized INS-1E cells, succinate and glycerol-3-phosphate increased mitochondrial ATP release which depends on exogenous ADP and P i.In the presence of substrates, addition of P i caused mitochondrial matrix … graph 2x+y -4WebThus, the insulin-mediated dephosphorylation of GS and phosphorylase involves both phosphatase activation and kinase inactivation. Insulin-stimulated glucose transport also plays a critical role in regulating GS, since removal of extracellular glucose markedly reduces the activation of GS by insulin (Brady et al., 1999a; graph 2y 2WebHigh blood glucose releases insulin, stimulating the translocation of specific glucose transporters to the cell membrane; glucose is phosphorylated to glucose 6-phosphate during transport across the membrane by ATP-D-glucose 6- phosphotransferase and non-specific hexokinase (ATP-D-hexose 6-phosphotransferase). graph 3 -2 and 1 -3WebWe found that insulin increases phosphate transport at 3 and 24 h. This effect was mediated by increased Vmax for phosphate transport but not Km. Because type III sodium-phosphate co-transporters Pit-1 and Pit-2 are found in VSMC, we examined their expression by Western blot and real-time RT-PCR. graph 2x-5y 10
