| Abstract: | A quantitative re-examination of the pteridines in Oncopeltus has given results at variance with those published previously. The precursors of the red pteridine, erythropterin, are xanthopterin and, probably, oxalacetic acid. Xanthopterin is not present as such in Oncopeltus eggs but exists as 7,8-dihydroxanthopterin. Chrysopterin and biopterin have also been isolated and identified from later growth stages of the bug. |
