Clii. Factors Influencing the Formation of Robison

COMPOUNDS which influence Robison ester formation from glycogen and inorganic phosphate in muscle extract may act either on the first step: glycogen + inorganic phosphate='glucose-l-phosphate (Cori ester)-or on the second step: Cori ester-+hexose-6-phosphate (Robison ester), or on both these steps. Several factors which increase or inhibit Robison ester formation could be shown to act on one or...

THE FORMATION OF GLUCOSE-l-PHOSPHORIC ACID IN EXTRACTS OF MAMMALIAN TISSUES AND OF YEAST

The initial stages of fermentation of glycogen to lactic acid in muscle have been investigated only recently. It was shown (1, 2) that the glycolytic reactions are initiated by the formation of glucose-l-phosphoric acid from glycogen and inorganic phosphate, an enzymatic process in which adenylic acid acts as coenzyme. The glucose-l-phosphoric acid (l-ester) is converted to glucose-6phosphoric ...

Lxxv. Studies in Glycolysis Ii. the First Stages of Glycolysis in Muscle Extract;

IN a previous communication [Kendal & Stickland, 1937, 1] it was shown that if rabbit muscle is minced and thoroughly washed with water, and then extracted several times with dilute Na2HPO4, the later extracts (usually the 4th) contain much of the glycolytic enzyme system but are freer from coenzymes than extracts prepared by earlier methods. This was shown by the fact that on addition of boile...

Succinic Acid Monoethyl Ester and Metformin Regulates Carbohydrate Metabolic Enzymes and Improves Glycemic Control in Streptozotocin-Nicotinamide Induced Type2 Diabetic Rats

Objective. Succnic acid mono ethyl ester (EMS) was recently proposed as an insulinotropic agent for the treatment of non-insulin dependent diabetes mellitus. In the present study the effect of EMS and Metformin on the activities of carbohydrate metabolic enzymes in streptozotocinnicotinamide induced type 2 diabeteic model was investigated. Methods. EMS were injected intraperitonially at doses 2...

THE ENZYMATIC CONVERSION OF GLTJCOSE-l-PHOS- PHORIC ESTER TO 6-ESTER IN TISSUE EXTRACTS*

The formation of glucose-l-phosphoric acid (l-ester) and its conversion to glucose-6-phosphoric acid have been shown to be initial steps in the degradation of glycogen to lactic acid (1). The enzyme which brings about the conversion of the l-ester has been found in extracts of rabbit muscle, brain, heart, liver, in dog and frog muscle extracts, and in extracts of yeast (2); it is presumably pre...
