Starch Phosphorylase of Potato
Cori and his colleagues (l-6) discovered and elucidated the series of reversible chemical reactions by which glucose is transformed into glycogen in animal tissues. These reactions are catalyzed by a group of enzymes, the most fundamental of which is phosphorylase, the enzyme which catalyzes the condensation of glucose-l-phosphate (Cori ester) to starch or glycogen. The properties of phosphoryl...
متن کاملDetermination of the structure of oligosaccharides prepared from acharan sulfate.
The fine structure of acharan sulfate, a recently discovered glycosaminoglycan isolated from Achatina fulica , was examined. This glycosaminoglycan has a major disaccharide repeating unit of -->4)-alpha-D-GlcNpAc(1-->4)-alpha-L-IdoAp2S(1--> (where GlcNpAc is N -acetylglucosamine, IdoAp is iduronic acid, and S is sulfate) making it structurally related to both heparin and heparan sulfate. Using ...
متن کاملStarch phosphorylase inhibitor from sweet potato.
A protein, starch phosphorylase inhibitor, was purified from the root of sweet potato (Ipomoea batatas [L.] Lam. cv Tainon 65). It had a molecular weight of 250,000 and could be composed of five identical subunits. The isoelectric point of the inhibitor was 4.63. It was a noncompetitive inhibitor toward the sweet potato enzyme with a K(i) value of 1.3 x 10(-6) molar when glucose-1-P was the var...
متن کاملThe gene structure of starch phosphorylase from sweet potato.
a-Glucan phosphorylases are of key importance among the enzymes controlling the entry of storage polysaccharides into the glycolytic pathway in microbes, animals, and plants. The enzymes catalyze the reversible phosphorolysis of cu-l,4-glucosidic linkages in glucan substrates. Among SP from higher plants, those from potato are best studied. They are classified into L and H types depending on th...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
