| Abstract: | - 1.1. Glycine, proline, and taurine are the quantitatively most important amino acid osmolytes in Penaeus aztecus postlarvae.
- 2.2. Taurine dominates the amino acid pool in low salinity, while proline dominates the amino acid pool at higher salinities.
- 3.3. Although not major contributors to the pool, glutamate and alanine are constitutively synthesized from 14C]glucose and 14C]glutamate under constant salinity and under hyperosmotic stress treatments.
- 4.4. Proline synthesis from 14C]-precursors is apparent under constant high (but not low) salinity and is significantly induced by hyperosmotic stress.
- 5.5. No appreciable glycine synthesis was observed from 14C]glucose or 14C]glutamate under any experimental conditions.
