We performed a detailed kinetic analysis of the uptake of dehydroascorbic acid by HL-60
cells under experimental conditions that enabled the differentiation of dehydroascorbic acid …

We studied the acquisition of dehydroascorbic acid by rat hepatocytes, H4IIE rat hepatoma
cells and Xenopus laevis oocytes. Transport kinetics and competition and inhibition studies …

Dehydroascorbic acid (DHA) is rapidly taken up by cells and reduced to ascorbic acid (AA).
Using the Xenopus laevis oocyte expression system we examined transport of DHA and AA …

It has been previously reported that glucose and its structural analogs inhibit
dehydroascorbic acid (DHA) transport across the membranes of nonpolar cells, which led to …

As the initial step in the use of fibroblasts as a model system for 'in situ kinetics', ascorbic
acid (vitamin C) accumulation in normal human fibroblasts was investigated for the first time …

It is unknown whether ascorbate alone (vitamin C), its oxidized metabolite dehydroascorbic
acid alone, or both species are transported into human cells. This problem was addressed …

A system for measuring the rate of transport of dehydroascorbate into human red blood cells
shows Michaelis-Menten type kinetics with substrate inhibition at levels above 150 muM …

Ascorbic acid (AA) is accumulated by various tissues such as adrenal glands, pituitary
gland, eye lens, as well as by leukocytes (TABLE l).','In order to achieve a concentration of …

Cellular ascorbic acid accumulation occursin vitro by two distinct mechanisms: transport of
ascorbate itself or transport and subsequent intracellular reduction of its oxidized product …

Dehydroascorbic acid (DHA), the first stable oxidation product of vitamin C, was transported
by GLUT1 and GLUT3 inXenopus laevis oocytes with transport rates similar to that of 2 …
