urate

Definitions

Examples

• Rarely, sodium urate occurs in crystalline form—slender prisms, arranged in fan- or sheaf-like structures (Fig. 32).

• It is possible—as in urate infarcts of infants—for urates to be molded into cylindric bodies within the renal tubules.

• The sediment usually contains abundant amorphous phosphates and crystals of triple phosphate and ammonium urate.

• Compare the terrestrial octopus, which makes armor-plating out of calcium urate instead of excreting urea or uric acid.

• Now dissolve the pure urate by washing it through the filter with a few cubic centimeters of the special nitric acid.
