Pungency in these onions is a market-based trait depending on consumers' preferences and it is normally measured by pyruvic acid content [19].

Lactate dehydrogenase is an oxidation reduction enzyme which reversibly catalyses the reaction between pyruvic acid and lactic acid.
As the key intermediate of glycolysis, pyruvic acid is the main constituent of energy metabolism and circulation and the center for metabolisms of carbohydrates, proteins and lipids in all tissues and organs of human body.10
Therefore, the purpose of this study was to evaluate six potential glycolytic modulators namely, pyruvic acid, oxalic acid, Zn acetate, sodium citrate, fructose diphosphate (FDP) and sodium bicarbonate on actively growing A549 (cancer) and MRC-5 (normal) cell lines.
Key components of the mesopeel age bionic recovery are pyruvic acid 36%, glycolic add 24%, lactobionic acid 4.8%, and shikimic add 4.8.
Pyruvic acid, that is produced by bacteria and implicated in the progression of caries, is oxidized by Ozone to acetate and carbondioxide.
3446 [cm.sup.-1] (OH stretching), 2931 [cm.sup.-1] (CH stretching) (DANTAS-SANTOS et al., 2012; ZHANG et al., 2008), 1652 [cm.sup.-1] (COO- or O-H stretching) (ZHANG et al., 2008), 1400-1404 [cm.sup.-1] (carboxyl group of the pyruvic acid stretching) and 1076 [cm.sup.-1] (arabinogalactan sulfate backbone stretching) (ESTEVEZ et al., 2009) were also observed in the IR spectra.
LDG enzyme plays an important role in converting lactic acid (the cause of muscle spasm and pain) into pyruvic acid. The aim of the research was to determine the toxic effects of commonly-used nanoparticles including gold, silver, and zinc oxide on LDH enzyme in rat body as a simulated sample for human body, and to compare the damage caused by those nanoparticles.
In some oleaginous fungus, excess of carbon source in the medium leads to over production of organic acids, such as pyruvic acid and several other products, to the detriment of lipids accumulation [55].
AbstractSeven a-keto acids pyruvic acid (PYR) 2-oxobutyric acid (KB) 3-methyl-2-oxobutyric acid(MKBA) 3-methyl-2-oxovaleric acid (K3MVA) 4-methyl-2-oxovaleric acid (K4MVA) 2- oxoglutaric acid (KG) and Phenyl pyruvic acid (PPY) as derivatives of 23-diamino-23- dimethybutane (DDB) were separated by HPLC column Zorbax C18 (4.6x150 mm-id).
Ethyl pyruvate (EP), a simple aliphatic ester derived from pyruvic acid, is safer and more stable than pyruvate (8).
(6) The ATP-creatine phosphate system is significantly depleted within 10-20 seconds, and therefore cytosolic glucose and glycogen are anaerobically catabolized (glycolysis pathway) to provide the muscles with ATPs to maintain the activity, with ultimate accumulation of pyruvic acid or lactic acid.
* Pyruvate and lactate (blood): Pyruvic acid is used to evaluate for possible disorders of mitochondria] metabolism.
