In the past there has been much confusion between the "distribution ratio" as defined above, the value of which varies with experimental conditions, ... and the "true partition coefficient" which is by definition invariable or the "partition coefficient" or "distribution constant" which apply to a particular chemical species under specified conditions. For this reason the terms "distribution constant," "partition constant," "partition coefficient," "partition ratio" and "extraction constant" should not be used in this context. 1, record 1, English, - distribution%20ratio

Dans le passé, il y a eu beaucoup de confusion entre l'expression «rapport de distribution» tel que défini [ci-dessus], dont la valeur varie avec les conditions expérimentales [...] et le «coefficient de partage vrai» qui, par définition, est invariable ou avec le «coefficient de partage» ou la «constante de distribution» qui s'appliquent à une espèce chimique en particulier, dans des conditions données.

Lipid soluble substances can enter a cell by dissolving in the lipid portion of the membrane and diffusing through it. The greater the lipid solubility, the more readily a molecule will pass through the membrane, i.e., the greater will be the flux for a given concentration difference. The oil-water partition coefficient (solubility in oil/solubility in water) gives a useful measure of lipid solubility. 4, record 3, English, - oil%2Fwater%20distribution%20ratio

The coefficient of oil/water distribution [is] also called the partition coefficient (abbreviated as P) ... The P value is typically presented as a logarithm of P (log P). It indicates how easily a chemical can be absorbed into or stored in fatty tissues in the body. The P value is also used to help determine the fate of the chemical in the environment through its tendency to partition into the water, soil and living organisms. 8, record 3, English, - oil%2Fwater%20distribution%20ratio
