- W3858705 abstract "Guanine (2-amino-6-hydroxypurine) and adenine (6-aminopurine) occur in all life forms as components of nucleic acids, nucleosides, nucleotides, and coenzymes in which they are bound by glycoside linkages. As degradation products of these compounds, guanine occurs in meat and in considerable concentrations in the scales and skin of fish. Free adenine is found in tea, sugar beets, yeast, and various animal organs. Guanine can be specifically deaminated to xanthine by guanase. Xanthine is oxidized to uric acid by xanthine oxidase. This chapter discusses the deamination of adenine with nitrous acid to obtain hypo-xanthine, which can be determined rapidly and accurately with xanthine oxidase. An increase in the uric acid content, as measured by the change in extinction at 293 nm, is proportional to the quantity of guanine or of adenine present. The complete oxidation of xanthine or hypoxanthine with xanthine oxidase is possible only if the buffer is sufficiently saturated with oxygen. The deamination of adenine to hypoxanthine is strongly dependent on the acid and nitrite concentration, and on the reaction time and temperature. The chapter describes the conditions in which the reaction proceeds completely to hypoxanthine." @default.
