摘要: Glycine was the most abundant free amino acid (FAA) in abdominal muscle of grass shrimp Palaemonetes pugio, accounting for over 50% total pool. Arginine, alanine, proline, taurine and serine were also present at relatively high concentrations. Following transfer from 17%. to 2 32%. S, new steady-state levels FAA observed 72 h. Total sum glycine, alanine proline exhibited a positive correlation with salinity. Exposure Aroclor 1254 did not have appreciable effects on levels, indicating that disruption intracellular osmoregulation major consequence PCB toxicity. However, changes individual concentrations exposed reflective an altered metabolic state. Glycine, which show immediately following exposure, underwent large decreases after PCB-free water indicated delayed effect exposure. A between salinity exist shrimp.
