Beta-Alanine Utilization of Ebony and Non-ebony Drosophila melanogaster

Abstract
Carbon-14-labeled β-alanine was injected into newly formed Drosophila melanogaster female pupae. Homozygous ebony deposited less C14in pupal sheaths, deposited more C14in adult body extracts and wings, and decarboxylated and oxidized β-alanine to excrete C14O2 faster than did non-ebony homozygotes. Heterozygotes were intermediate in all these activities.
