Hello again,

Another question regarding carotenoids... (by the way thanks a lot Dr.
Leray, both for your excellent and comprehensive website and also for
this discussion group).
I've seen in a paper that Kow values (octanol-water partitioning
coeficient) were given for carotenoids (and lipid soluble vitamins) in
the range of 12-14 (values estimated from the model KOWWIN developped
by Syracuse university, NY). Is it a common practice in lipid sciences
to express the hydrophobicity of a compound using Kow values?
I am wondering at first because I am an environmental scientist and we
use this chemodynamic value to express the behaviour of an
anthropogenic contaminant such as PCBs, PAHs... also because as far
as I know a Kow value of more than 8-9 is out of the "experimental
scale"...
Thanks
Maxime
