Evidence for chemically shifted water in the brine shrimp, (Artemia): possible interpretations.

We report in this paper evidence for the existence of an unusually large chemical shift for intracellular water proton in brine shrimp (Artemia). The observed chemical shift, when corrected for bulk susceptibility, is down field 0.11 ppm from the pure water signal. The possible origin of such large chemical shift for intracellular water in this system is discussed.
