Alginate was synthesized principally from degradation products of glucose, whereas the majority of the polymer produced from fructose was assembled from intact hexose units. A possible explanation for the limited synthesis of alginate from undegraded glucose molecules is that one of the necessary enzymes, glucose-phosphate isomerase, is subject to inhibition by 6-phosphogluconate, a metabolite involved in the catabolism of sugars via the Entner-Doudoroff pathway in both of the organisms.", }
