Incorporation of Glucose into an Insoluble Polyglycoside during Oscillatory Controlled Glycolysis in Yeast Cells

Abstract

In the first few minutes of oscillatory controlled glycolysis yeast cells convert 50% of all glucose taken up into ethanol and glycerol, and incorporate 80–90% of the rest into some in‐soluble polyglycoside. Glucose uptake in glycolysing yeast cells is a pulsatory process which is in phase with fruc‐tose‐1,6‐diphosphate synthesis. The concentration of UDPG, an intermediate in polyglucoside synthesis, is oscillating in phase with glucose‐6‐phosphate. The cells use 80–90% of all ATP synthesized in glycolysis for uptake and storage of glucose.
