A major metabolite of vitamin B6. High pyridoxic acid indicates high recent intake of vitamin B6. Because some individuals may require very high doses of vitamin B6, high values do not necessarily indicate the need to reduce vitamin B6 intake. Low values are associated with low B6 status, high oxalates, and/or low neurotransmitters.

Pyroglutamate (or Pyroglutamic acid) is an intermediate in the glutathione metabolism and a marker of glutathione deficiency.

Pyroglutamate (or Pyroglutamic acid) is an intermediate in the glutathione metabolism and a marker of glutathione deficiency.

Pyroglutamate is a step in the production/recycling of glutathione. Glutathione is one of the most potent anti-oxidants in the human body. It is especially important in getting rid of toxins, including the harmful metabolites of estrogen detoxification 4-OH-E1 and 4-OH-E2.

In healthy individuals, a very modest amount of Pyroglutamate is spilled in the urine.

Pyroglutamate (or Pyroglutamic acid) is an intermediate in the glutathione metabolism and a marker of glutathione deficiency.

Pyroglutamate is an intermediate in glutathione recycling and production. Glutathione requires the amino acids cysteine, glycine and glutamate for production. If the body cannot convert pyroglutamate forward to glutathione, it will show up elevated in the urine. High pyroglutamate is an established marker for glutathione deficiency. Remember that glutathione is one of the most potent antioxidants in the human body and is especially important in getting rid of toxins including the reactive quinone species formed by 4-OH-E1 and 4-OH-E2. This reactive species can damage DNA if not detoxified by either methylation or glutathione.

Pyroglutamic acid (5-oxoproline) is produced and utilized in the gamma-glutamyl cycle. This cycle is needed to assist in the production and recycling of glutathione (GSH), a powerful antioxidant.

Glutathione is a tripeptide, consisting of glutamate, cysteine, and glycine. Using the gamma-glutamyl cycle, GSH is divided into cysteinyl glycine and a gammaglutamyl molecule which attaches to another amino acid for transport across a membrane or into a cell. Gammaglutamyl transferase then splits off that attached amino acid, and the glutamate becomes pyroglutamic acid (5-oxoproline).

Cysteinyl glycine is also broken down and transported into the cell as cysteine and glycine. The entire GSH molecule needs to be reformed intracellularly from pyroglutamic acid by recombining cysteine, glycine, and glutamic acid using GSH synthetase.

This enzymatic reformation requires cofactors such as ATP and magnesium.

Pyruvate or pyruvic acid is an intermediate in several metabolic pathways. Abnormalities in pyruvate alone are not diagnostic of any disease, but they are clinically useful when measured with lactate deform the lactate to pyruvate ratio.

Pyruvate is a key player in energy metabolism, serving as a critical intermediate in the glycolytic pathway, where glucose is converted into pyruvate, and subsequently, pyruvate plays a central role in the Citric Acid Cycle (CAC), also known as the Krebs cycle. Elevated pyruvate levels on the panel can indicate a range of metabolic challenges and disruptions. High pyruvate levels may arise due to factors such as nutritional inhibitions affecting enzymes involved in pyruvate breakdown, the presence of low-activity enzyme variants inherited genetically, an abundance of precursor molecules like glucose and amino acids, or elevated levels of downstream products like lactate and citrate.

Pyruvate feeds into the citric acid cycle & converts into acetyl CoA. Pyruvate is formed from carbohydrate via glucose or glycogen & secondarily from fats (glycerol) & glycogenic amino acids.
