A note on solubility

Examine will soon include a little header to quickly denote if a compound is wholly water soluble or wholly fat soluble (or a mixture of the two). Until then, take the following to heart.

  • If studies emphasize an ethanol extract for a compound, it is fat soluble to a degree

  • If an ethanol extract is never used, it is most likely water soluble

  • If the compound is classified as 'highly polar' it is usually very water soluble, the opposite can also be true (highly non-polar == fat soluble)
