Abstract

Evidence is presented which necessitates a modification of the hypothesis proposed earlier (J., 1945, 877) whereby the synthesis of amylopectin from glucose-1 phosphate was pictured as involving the intermediate formation of short unbranched chains of glucose units (pseudoamylose). It is now shown that the synthesis proceeds as follows: Glucose-1 phosphate ⇄ Phosphorylase Amylose →Q-enzyme Amylopectin.
