Description

Application

Pyruvic acid was used to study the cultivation of previously undescribed soil bacteria as micro colonies using soil substrate membrane system. Pyruvic acid was used to develop a new method for simultaneous determination of organic acids in red wine and must using liquid chromatography.

Biochem/physiol Actions

Pyruvic acid reacts with N-acetyl mannosamine by an aldol-type condensation to form sialic acid. Pyruvic acid is a component of commercial red seaweed polysaccharide. In muscle, pyruvic acid (derived from glycogen) is reduced to lactic acid during exertion, which is reoxidized and partially retransformed to glycogen during rest.
