osmole

 [oz´mōl]
a unit of osmotic pressure equivalent to the amount of solute that dissociates in solution to form one mole (Avogadro's number) of particles (molecules and ions). Symbol Osm.

os·mole

(oz'mōl),
The molecular weight of a solute, in grams, divided by the number of ions or particles into which it dissociates in solution.

osmole

/os·mole/ (oz´mol) a unit of osmotic pressure equivalent to the amount of solute that dissociates in solution to form one mole (Avogadro's number) of particles (molecules and ions). Symbol Osm.

osmole

[os′mōl]
Etymology: Gk, osmos, impulse, osis, condition + mole (molecule)
the quantity of a substance in solution in the form of molecules, ions, or both (usually expressed in grams) that has the same osmotic pressure as one mole of an ideal nonelectrolyte. Also spelled osmol. -osmolal, adj.

osmole

Physiology A volume-regulating organic solute that may accumulate in high concentrations in a cell without adverse effects on the cell's structure or function. See Idiogenic osmole.

os·mole

(oz'mōl)
The molecular weight of a solute, in grams, divided by the number of ions or particles into which it dissociates in solution.

osmole

The standard unit of osmotic pressure. The osmole is equal to the molecular weight of the dissolved substance expressed in grams divided by the number of particles or IONS into which each molecule of the substance dissociates in solution.

osmole

the amount of a substance in a solution that forms one mole of osmotically active particles, irrespective of their size, e.g. a single sodium ion contributes as much to the osmolality as a large protein molecule; and 1 mole of glucose, which does not ionize, provides 1 osmole, while 1 mole of sodium chloride provides 2 osmoles - one of Na+ and one of Cl-.

osmole

a unit of osmotic pressure equivalent to the amount of solute substances that dissociates in solution to form one mole (Avogadro's number) of particles (molecules and ions). Abbreviated Osm.
