Differential Glucose Incorporation into Glycogen by Hymenolepis diminuta

Differential glucose incorporation into glycogen by Hymenolepis diminuta.

1. A differential incorporation of 14C-glucose into two distinct molecular weight fractions of glycogen from the tapeworm Hymenolepis diminuta has been observed. Changes in these labeling patterns as a function of the glycogen level have been examined. 2. After incubation of Hymenolepis diminuta in media containing 14C-glucose under steady state conditions of glycogen metabolism, the specific a...

The anaerobic incorporation of 32P into adenosine triphosphate by Hymenolepis diminuta.

The anaerobic incorporation of 32P into ATP by the tapeworm Hymenolepis diminuta was studied in the presence and absence of uncouplers of oxidative phosphorylation and anticestodal agents. Low concentrations of all compounds tested inhibited this incorporation. Under the anaerobic conditions employed, internal ATP concentrations remained constant in spite of the inhibition of the incorporation ...

Localization of Glycogen in the Cestode, Hymenolepis Diminuta

Glycogen isolated from the rat tapeworm Hymenotepis diminuta by a mild quantitative procedure exhibits a sedimentation coefficient distribution characterized by two distinct regions of molecular weight with mean S values of 200 X 10-13 cm/dyne, see and 1500 X 10-13 cm/dyne, see respectively (17). This distribution is characteristic for the physiological state of the organism, and differences in...

Studies on Malic Enzyme from Hymenolepis Diminuta

Differential Incorporation of Glucose into Biomass during Warburg Metabolism

It is well established that most cancer cells take up an increased amount of glucose relative to that taken up by normal differentiated cells. The majority of this glucose carbon is secreted from the cell as lactate. The fate of the remaining glucose carbon, however, has not been well-characterized. Here we apply a novel combination of metabolomic technologies to track uniformly labeled glucose...
