Effects of glucose on glycogen synthetase, phosphorylase, and glycogen deposition in the perfused rat liver.
An increase in the perfusate glucose concentration from near zero to about 11 mM increased glycogen synthesis in the perfused, isolated rat liver from zero to a value about half the maximum seen in the intact animal. Increased synthesis appeard to due not only to provision of substrate but also to conversion of glycogen synthetase to the active form and of glycogen phosphorylase to the inactive...
متن کاملDistribution of radioactive carbon dioxide incorporated into rat liver glycogen.
It has been demonstrated that Cl402 administered to fasted rats (2) or incubated with liver slices from fasted animals (3) yields glycogen which is labeled predominantly in carbon atoms 3 and 4. These findings are consistent with the interpretation that CO2 incorporation into glycogen proceeds by a reversal of the anaerobic glycolytic pathway (4). However, during the past several years it has b...
متن کاملHomogeneous glycogen synthetase b from rat liver.
Glycogen synthetase b has been purified about 2,000-fold from a crude extract of rat liver. The purification procedure consisted of the separation of the glycogen pellet by centrifugation, solubilization of the synthetase by phosphorolysis of the glycogen by endogenous phosphorylase, and adsorption and elution from Ca3(P04)2 gel. The final material appears homogeneous on gel electrophoresis. A ...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولGlycogen synthesis in rat liver from a pool of free glucose.
Glycogen synthesis in isolated perfused livers or livers of anesthesized rats (in situ), was studied using radioactively labelled fructose, lactate, and inositol as substrates. The specific radioactivity of glucose and glycogen was measured at various times and compared with that of some intermediates. The results suggest that liver glycogen is formed from the pool of free glucose which in turn...
