Summary
In vivo studies of the incoporation of [U-14C]glycine into purine nucleotides have established the de novo pathway for purine biosynthesis in Artemia sp. during the early period of larval development. This pathway can be modified by the salt concentration of the incubation media. In addition, Artemia of different geographical origins may differ with respect to the detection, functionality and variability of this metabolical pathway.
