One of the most important diketones
is diacetyle (butan-2, 3-dione) with sweet buttery and vanilla aroma.
Because diacetyl and 2,3-pentanedione, both diketones
, are chemically very similar, Morgan suspected that inhaled 2,3-pentanedione may be toxic to the respiratory tract as well.
Effects of plant antioxidants and natural vicinal diketones
on methane production, studied in vitro with rumen fluid and a polylactate as maintenance substrate.
In the light of the information referred to above we made an attempt to obtain diketones
2 and 3 directly from lactone 1 by hydroboration (Scheme 2).
reports that key company experiments have revealed the bridging effects of ligands, such as 1, 3 diketones
, that hold together different interacting metals, such as barium and zinc.
During the wort fermentation period, several reactions closely related to cytoplasmic membrane occur in yeast, among them are: nutrients uptake, metabolic by-products extrusion, respiratory activity, vicinal diketones
The samples of PVOH exposed to the Phanerochaete chrysosporium enzymes during 5 days showed deterioration, which implies changes in the chemical structures (oxidation or loss of small fragments) since in the UV signals show the possible formation of enolized [Beta] diketones
