Chapter 14, Problem 1MTE

Summary Introduction

To determine: The metabolic pathway in which uric acid is used as an intermediate.

Concept introduction:

Uric acid is heterocyclic purine derivatives produced from the metabolic breakdown of purine nucleotides. Purines are normally synthesized in the body and found in some drinks and foods. The enzyme xanthine oxidase oxidizes oxypurines into uric acids. It is an end product in the nitrogen metabolism of reptiles and birds.

Summary Introduction

To explain: Whether the purine metabolic pathway differs among the species.
