Component
Hydrophobicity of an anaesthetic agent
Hydrophobicity of an anaesthetic agent. Species, exposure and limitations are retained in each linked claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
Where it participates (unsigned role)
The GABA-A receptor and hypnotic potencies of etomidate and the etomidate analogs ranged by 91-fold and 53-fold respectively, these potency measurements were significantly correlated with r = 0.72, but neither measurement correlated with drug hydrophobicity with r = 0.019 and 0.005 respectively, statistically significant and predictive comparative molecular field analysis models were generated, and a pharmacophore model was built revealing both the structural elements associated with high potency and the interactions that these elements make with the etomidate-binding site.
