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.

Methodology has been developed to reconstitute carotenoids and bacteriochlorophyll alpha with isolated light-harvesting complex I (LHI) polypeptides of both Rhodobacter sphaeroides and Rhodospirillum rubrum. Reconstitution techniques first developed in this laboratory using the LHI polypeptides of R. rubrum, R. sphaeroides
