Phosphoenolpyruvic acid (Phosphoenolpyruvate) is a glycolysis metabolite with a high-energy phosphate group. Phosphoenolpyruvic acid is involved in glycolysis and gluconeogenesis, and used as energy source to produce ATP, under the energy-limited conditions. Phosphoenolpyruvic acid also exhibits cytoprotective and anti-oxidative properties[1].

ChEBI: Phosphoenolpyruvic acid is a monocarboxylic acid that is acrylic acid substituted by a phosphonooxy group at position 2. It is a metabolic intermediate in pathways like glycolysis and gluconeogenesis. It has a role as a fundamental metabolite. It is a monocarboxylic acid and a carboxyalkyl phosphate. It is functionally related to an acrylic acid. It is a conjugate acid of a phosphonatoenolpyruvate and a phosphoenolpyruvate.
