The excretion of allantoin, hypoxanthine
Determination of hypoxanthine
in fish meat with an enzyme sensor.
reducing XDH converted to oxygen-reducing XOD, when tissue reperfused (molecular oxygen reintroduced into the tissues), oxygen interacts with hypoxanthine
and XOD to produce ([O.
Despite these potential benefits of the blood cardioplegia, other studies suggested increased oxidative stress by either iron overload  or increase of hypoxanthine

Cord plasma vasopressin, erythropoietin and hypoxanthine
as indices of asphyxia at birth.
In 2000, it was shown that 5-methyltetrahydrofolate (5-MTHF), the main circulating folate in the body, directly scavenged superoxide generated by the xanthine/ hypoxanthine
The mode of action of barley feeding may be attributed to hypoxanthine
available in barley grains which is reported to have demulcent, bitter tonic and astringent activity.
Other maturation-preventing factors in follicular fluid are oocyte maturation inhibitor (57) and hypoxanthine
, (58) which acts only in combination with cAMP.
Xanthine Oxidoreductase (XOR) is a rate-limiting enzyme of the purine degradation pathway, oxidizing hypoxanthine
into xanthine and xanthine into uric acid.
However, in the case of uric acid, xanthine and hypoxanthine
and the high activity of the enzyme xanthine oxidase, which converts hypoxanthine
and xanthine into uric acid, the excretion of allantoin and uric acid is approximately 98% of urinary purine derivatives.
