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

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.

Osmolarity is a measure of osmoles solute per kg solvent (water in the present study).
La osmolalidad de una solucion es el numero de osmoles de soluto por kg de solvente, en tanto que osmolaridad es el numero de osmoles de soluto por litro de solucion.
However, as [U.sub.sg] depends on the total osmotic load consumed and the number of osmoles in vitamin tablets is small compared to the total osmotic load of daily food intake, vitamin ingestion does not influence [U.sub.sg] (Armstrong, personal communication.
The brain generates compounds called ideogenic osmoles, which raise intracellular osmolality and minimize brain shrinkage (Kokko, 2000; Marino 1998).
Mean urinary osmolality for this standard pool (n = 36) was 0.820 Osm/kg (osmoles per kilogram) with an RSD of 1.65%.
This case describes a more unusual cause of hyponatremia, so-called beer potomania (2), in which free-water (out of proportion to osmoles) ingestion is the culprit.
Examples of important "osmoles" in serum and cells are sodium, glucose, and urea (BUN).
