Über die Herkunft der C‐Atome 2 und 8 der Harnsäure bei Drosophila melanogaster

Abstract
Uric acid has been isolated from adult Drosophila melanogaster fed with glucose‐[1‐14C] and glucose ‐[6‐14C]. The specific activities of carbon 2 and 8 of the purine skeleton were considerably higher after feeding glucose‐[6‐14C] than after glucose‐[1‐14C]. The same experiments with serine‐[1‐14C] and serine‐[3‐14C] have shown that the C‐3 of serine leads to high activities of C‐2 and C‐8 of the purine ring.
