Get Free Quote in 24hPhosphoenolpyruvate (PEP), chemically known as 2-phospho-D-glyceric acid enol form or more precisely (Z)-3-phosphonooxyprop-2-enoyl phosphate, is a critical high-energy phosphate ester in cellular metabolism. With the molecular formula C3H5O6P and a molecular weight of 168.04 g/mol, PEP serves as a pivotal intermediate in glycolysis, gluconeogenesis, and the biosynthesis of amino acids like phenylalanine and tyrosine.
In glycolysis—the primary pathway for carbohydrate catabolism in living organisms—PEP is generated from 2-phosphoglycerate via the enzyme enolase. This step creates a high-energy enol phosphate bond, which is subsequently hydrolyzed by pyruvate kinase to produce pyruvate and ATP. This reaction yields approximately 31.4 kJ/mol of free energy under standard conditions, making PEP one of the highest-energy phosphates in metabolism, surpassed only by phosphocreatine and ATP itself.
Structurally, PEP features a phosphate group esterified to the enol form of pyruvate, rendering it unstable in aqueous solutions and prone to spontaneous hydrolysis to pyruvate and inorganic phosphate. Its pKa values (around 6.3 for the enol and lower for phosphates) ensure reactivity at physiological pH. Commercially, high-purity phosphoenol pyruvate (often >98%) is synthesized via enzymatic or chemical routes, including from pyruvate using PEP synthetase or acetyl phosphate-mediated methods.
Applications of phosphoenolpyruvate span biotechnology, pharmaceuticals, and research. In enzyme assays, PEP is a substrate for pyruvate kinase (PK), phosphoenolpyruvate carboxylase (PEPC), and PEP carboxylase, enabling quantification of metabolic fluxes. It's integral to coupled assays measuring ATP-dependent enzymes like hexokinase or firefly luciferase. In metabolic engineering, PEP is used in cell-free systems for ATP regeneration and in the production of shikimate pathway metabolites for herbicides like glyphosate.
Industrially, demand for buy phosphoenolpyruvate surges in the USA's biotech sector, where it's vital for recombinant protein production, biofuel research, and synthetic biology. For instance, in E. coli fermentations, PEP levels dictate carbon flux toward aromatic compounds. Purity is paramount: impurities like pyruvate or metal ions can inhibit downstream enzymes, leading to 20-30% yield losses.
Regulatory compliance for phosphoenolpyruvate supplier USA includes FDA guidelines for research chemicals (21 CFR 184), ensuring no heavy metals (<10 ppm) or microbial contaminants. Our GMP-certified production adheres to USP/EP monographs, with COA including HPLC purity (>99%), NMR verification, and endotoxin levels <0.1 EU/mg.
Historically, PEP was first isolated in 1930s by Lohmann and Meyerhof during muscle extract studies, but its role exploded post-1950s with Embden-Meyerhof-Parnas pathway elucidation. Today, global market size for biochemical intermediates like PEP exceeds $500M annually (Statista 2025 data), driven by CRISPR workflows and personalized medicine.
In-depth kinetics: The pyruvate kinase reaction follows Michaelis-Menten with Km ~0.1-1 mM for PEP, modulated by allosteric effectors like fructose-1,6-bisphosphate. Stability data shows PEP solutions (pH 7.0, 4°C) retain 90% activity after 7 days, but lyophilized powder is preferred for shipping. For USA importers, our high purity phosphoenolpyruvate arrives via FedEx/DHL in 5-7 days, with triplicates stability testing.
LSI relevance: As a glycolysis intermediate, PEP intersects with carbohydrate metabolism, ATP regeneration, pyruvate kinase substrate, biochemical reagent, enolase product, shikimate pathway, cell-free synthesis, metabolic flux analysis, enzyme coupled assay, high-energy phosphate, gluconeogenesis substrate, amino acid biosynthesis, biotech intermediate, and research chemical.
