General description

2-Thiobarbituric acid is a molecule made up of heteroatoms: nitrogen, sulphur and oxygen.

Application

2-Thiobarbituric acid has been used to measure malondialdehyde (MDA) in lipid peroxidation assay.

Biochem/physiol Actions

2-Thiobarbituric acid (TBA) is useful to quantitate lipopolysaccharides, carrageenan, and sialic acids. It is also used to detect lipid hydroperoxides and lipid oxidation. It has applications in the field of medicine and biochemistry. TBA may possess the ability to prevent metal corrosion.
