How the body processes this drug — absorption, distribution, metabolism, and elimination
Some ascorbic acid is metabolized to inactive compounds including ascorbic acid-2-sulfate and oxalic acid.
Proteins and enzymes this drug interacts with in the body
PMID:10556483 PMID:10556521 PMID:10631088 PMID:36749388
Has retained some ancestral activity toward nucleobases such as urate, an oxidized purine. Low-affinity high-capacity sodium:urate cotransporter, may regulate serum urate levels by serving as a renal urate re-absorber PMID:36749388
PMID:10471399 PMID:10556521
Mediates electrogenic uptake of vitamin C, with a stoichiometry of 2 Na(+) for each ascorbate PMID:10471399
PMID:10744784 PMID:12031666 PMID:12923223 PMID:9326939
Does not hydroxylate long and very long straight chain acyl-CoAs or 2-methyl- and 4-methyl-branched acyl-CoAs PMID:10744784 PMID:12923223

Has a very broad substrate specificity; can transport a wide range of aldoses including both pentoses and hexoses .
PMID:18245775 PMID:19449892
Most important energy carrier of the brain: present at the blood-brain barrier and assures the energy-independent, facilitative transport of glucose into the brain .
PMID:10227690
In association with BSG and NXNL1, promotes retinal cone survival by increasing glucose uptake into photoreceptors (By similarity). Required for mesendoderm differentiation (By similarity)
PMID:26176916 PMID:32860739 PMID:9477959
Can also mediate the uptake of various other monosaccharides across the cell membrane .
PMID:26176916 PMID:9477959
Mediates the uptake of glucose, 2-deoxyglucose, galactose, mannose, xylose and fucose, and probably also dehydroascorbate .
PMID:26176916 PMID:9477959
Does not mediate fructose transport .

Proteins that carry this drug through the body
PMID:19021548
Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity).
Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity).
Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli .
PMID:6234017
Does not prevent iron uptake by the bacterial siderophore aerobactin PMID:6234017
