General description

Hexafluoroacetone trihydrate forms crystalline 1:1 complexes with imidazole 3-oxides.

Application

Hexafluoroacetone trihydrate was used to study the kinetics and thermodynamics of linkage isomerization of (acetone)pentaammineruthenium (III) and-ruthenium (II) complexes. It was used in a study to reconstitute the α-and β-polypeptides of both Rhodobacter sphaeroides and Rhodospirillum rubrum with bacteriochlorophyll a.

The prion protein (PrP) undergoes a profound conformational change when the cellular isoform (PrPC) is converted into the scrapie form (PrPSc). Limited proteolysis of PrPsc produces PrP 27-30 which readily polymerizes into amyloid. To study the structure of PrP amyloid
