1976 Amer. Jrnl. Physiol. 231 848 The effect of three monosaccharides, three disaccharides, two dipeptides, combinations of tryptophan with two hexoses, one hexitol, and two amino acids on gastric emptying was studied in dogs to further define the small intestinal receptors responsive to osmolytes and tryptophan.

1984 Biol. Bull. 167 495 Instead, Elysia utilizes an osmolyte previously unknown for animals, proline betaine.

1986 Jrnl. Exper. Biol. 123 345 Ureteral urine from birds in both groups was usually strongly..hypertonic to plasma, but sodium, potassium and chloride concentrations were low and constituted less than 25% of total osmolytes.

1997 G. S. Helfman et al. Diversity of Fishes vii. 91/1 The elasmobranch strategy of offsetting high external ionic concentrations with elevated levels of organic osmolytes such as urea is also used by..the coelacanth.., as well as the crab-eating frog.
