1. Radioactivity was found to be associated with purine ribonucleotides in extracts of gravid adult Angiostrongylus cantonensis from the lungs of rats when the parasite was incubated in a medium containing [14C]glycine. 2. The rate of incorporation was at least 0.2 pmole/min per mg of parasite and approximately equal amounts of adenine and guanine ribonucleotides were synthesized. 3. This is the first demonstration of the capacity for a mammalian parasitic helminth to synthesize purines de novo.

UI	MeSH Term	Description	Entries
D007042	Hypoxanthines	Purine bases related to hypoxanthine, an intermediate product of uric acid synthesis and a breakdown product of adenine catabolism.
D007288	Inosine	A purine nucleoside that has hypoxanthine linked by the N9 nitrogen to the C1 carbon of ribose. It is an intermediate in the degradation of purines and purine nucleosides to uric acid and in pathways of purine salvage. It also occurs in the anticodon of certain transfer RNA molecules.
