Description
A non-essential amino acid central to the urea cycle and aspartate-glutamate transamination. Used as the precursor for aspartame manufacturing, in pharmaceutical applications, and as a chelating agent in mineral supplement formulations.
White crystalline powder. Slightly water-soluble; freely soluble in acid and alkaline solutions.
We supply food-grade and pharmaceutical-grade L-Aspartic Acid from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include Standard Food Grade (FCC compliant 98.5 percent), Pharmaceutical Grade meeting BP/USP/EP/JP specifications, Aspartame-Synthesis Grade (used as feedstock for aspartame manufacturing), and Magnesium Aspartate / Potassium Aspartate / Calcium Aspartate (chelated mineral supplement forms).
Bulk and reduced-MOQ shipments. Batch-level COA covering assay, specific rotation, related amino acids, heavy metals, and microbiology.
Introduction
L-Aspartic Acid is a non-essential amino acid that the body produces from oxaloacetate through transamination. It is one of the two amino acid components of aspartame (the other being L-phenylalanine), which is the dominant commercial application.
Industrial production proceeds primarily by enzymatic synthesis from fumaric acid using aspartate ammonia lyase, yielding the natural L-enantiomer at high purity. Alternative routes from microbial fermentation are also commercial.
Recognized as a permitted food ingredient by the U.S. FDA, the European Food Safety Authority, and equivalent regulators worldwide. Listed in BP, USP, EP, and JP pharmacopoeias.
Strategic positioning combines the dominant aspartame-synthesis application (which consumes the largest single volume), pharmaceutical and clinical nutrition use, and supplement and mineral-chelation applications across the broader market.
Where it is used
- Manufacturing feedstock for aspartame production: the largest single use globally
- Pharmaceutical applications: parenteral nutrition, hepatic-support formulations
- Mineral chelation: magnesium, potassium, and calcium aspartate supplements
- Sports nutrition: stamina and recovery-positioned supplements
- Animal feed amino-acid fortification
- Specialty pharmaceutical applications including specific clinical-nutrition products
- Infant formula manufacturing
