Anwendungen

Pyruvic acid is used as a component in culture broths and media as commercial red seaweed polysaccharide. It is involved in the construction of amino acid alanine as well as supplies energy to living cells via citric acid cycle (Krebs cycle). It reacts with N-acetyl mannosamine by an aldol-type condensation to prepare sialic acid. It is employed to study the cultivation of soil bacteria as micro colonies using soil substrate membrane system. It finds application in liquid chromatography and in the determination of organic acids in red wine.

Bemerkungen

Store in cool place. Incompatible with strong oxidizing agents, strong bases and reducing agents.
