1.Determination of hypoxanthine and xanthine in fish by the coupled reaction of enzyme (fluorometric method)
2.PEROXIDATION EFFECTS ON LIPOSOME OF ACTIVE OXYGEN SPECIES PRODUCED BY THE SYSTEM OF ADP-FeCl_3-XANTHINE-XANTHINE OXIDASE
3.ESR spectrum of hypoxanthine-xanthine oxidase and Fe ++ —H 2O 2 system were significantly reduced or disappear by NADH.
4.A white powder, C5H4N4O, that is an intermediate in the metabolism of animal purines.
5.Tea contains, in addition to caffeine, small amounts of two other methyl xanthines, theobromine and theophylline, 3,7 -dimethy1 and 1,3-dimethy1 xanthine, respectively.
6.Methods:The experimental model was based on bovine RPE cells which were maintained in monolayer culture. Hypoxanthine/Xanthine oxidase (HX/XO) served as the radical generating system.
7.A Study on the Relationships of IMP and Collagen Content with Pork Quality
8.The hypoxanthine contents in BEK,EK,Dilong and fresh earthworm are 1.4612%,0.9967%,0.9375% and 0.1185% respectively.
9.A yellowish-white, crystalline purine base, C5H4N4O2, that is a precursor of uric acid and is found in blood, urine, muscle tissue, and certain plants.
10.This paper reports the separation and de-termination of xanthine,guanine,3denine,theophylline and caffeine on a Spherisorb C_(18)column with CH_3OH-KH_2PO_4-Na_2HPO_4 buffersolution(PH=8.2)as a mobile phase,Thismethod was used for the determination of caf-feine in beverages.
