| capillary electrophoresis of pterin derivatives responsible for the warning coloration of heteroptera. | a new capillary electrophoretic (ce) method has been developed for analysis of 10 selected derivatives of pterin that can occur in the integument (cuticle) of true bugs (insecta: hemiptera: heteroptera), specifically l-sepiapterin, 7,8-dihydroxanthopterin, 6-biopterin, d-neopterin, pterin, isoxanthopterin, leucopterin, xanthopterin, erythropterin and pterin-6-carboxylic acid. pterin derivatives are responsible for the characteristic warning coloration of some heteroptera and other insects, signa ... | 2014 | 24602308 |
