Stable isotope incorporation evidence for a polyacetate origin of the acyl residues in triophamine, a diacylguanidine metabolite obtained from the dorid nudibranch Triopha catalinae

Abstract

Biosynthetic feeding experiments with sodium [1,2-¹³C₂]-acetate have shown that the acyl residues of triophamine 1 are formed de novo in Triopha catalinae from five intact acetate units.
