Mannose metabolism in the human erythrocyte.

The metabolism of mannose by human erythrocytes has been investigated. Phosphorylation of mannose is achieved by an enzyme with electrophoretic mobility on starch gel indistinguishable from the glucose-phosphorylating enzyme. Mannose phosphorylation is competitively inhibited by glucose; glucose phosphorylation is competitively inhibited by mannose. The K(i) values of inhibition are similar to ...

Ascorbate function and metabolism in the human erythrocyte.

Ascorbic acid, or vitamin C, is an important antioxidant in plasma, where it consumes oxygen free radicals and helps to preserve alpha-tocopherol (vitamin E) in lipoproteins. Erythrocytes, as the most plentiful cell in blood, help to preserve ascorbate in the blood plasma. In contrast to nucleated cells, which avidly concentrate ascorbate, the erythrocyte ascorbate concentration is the same as ...

Erythrocyte Metabolism

Previous studies from this laboratory on the preservation of erythrocytes stored in vitro have shown that the storage lesion, as characterized by the decline in level of organic phosphate esters, may be reversed by incubating the aged cells with certain purine nucleosides (1). Pyrimidine nucleosides were ineffective in this respect, as was the addition of the purine bases and ribose, alone or i...

Studies of the metabolism of human erythrocyte membranes.

These investigations were undertaken to discover whether the membrane of the mature human erythrocyte is capable of metabolic activity that could possibly provide the means for active transport. Hoffman (2) has clearly shown that ATP provides energy for sodium transport, and it has been assumed that ATP for this process is supplied from within the erythrocyte. It seemed reasonable to examine me...

Erythrocyte Energy Metabolism in Hereditary

The incorporation of extracellular orthophosphate-32P into cellular ATP, 2,3-diphosphoglyceric acid, and inorganic phosphate has been measured over a period of 6 hours in vitro in red blood cells from normal subjects and from patients with hereditary spherocytosis who had undergone splenectomy. The pattern of labeling of the intracellular compounds was found to be the same in both types of red ...
