Anwendung

Trichloroacetic acid (TCA) can be used as a catalyst to synthesize:
  • β-enaminones via condensation reaction of 1,3-dicarbonyl compounds and amines.
  • 6-amino-3-methyl-1,4-diphenyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile derivatives via four-component condensation reaction of ethyl acetoacetate, phenylhydrazine, malononitrile, and aromatic aldehydes.
  • Tetrahydrobenzo[a]xanthen-11-ones by three-component reaction of aldehydes, 2-naphthol and dimedone.

Traditionell zur Fällung von Proteinen verwendet. Zur Bestimmung der Proteinkonzentration durch quantitative Fällung. Zum Entkalken und als Fixationsmittel in der Mikroskopie verwendet.

The ratio of the nitric oxide synthase (NOS) cofactor tetrahydrobiopterin (BH(4)) to its oxidized form dihydrobiopterin (BH(2)) has been suggested as an index of endothelial dysfunction. Consequently, much effort has been put into preserving the in vivo equilibrium between these

After diabetes, the heart has a singular reliance on fatty acid (FA) for energy production, which is achieved by increased coronary lipoprotein lipase (LPL) that breaks down circulating triglycerides. Coronary LPL originates from cardiomyocytes, and to translocate to the vascular
