L-Aspartic acid by MP Biomedicals is a high purity amino acid. Also known as aspartate, which contains an -amino acid an amino group and a carboxylic acid. This preparation is available as a white powder which is soluble in water. Aspartate can be synthesized by the body, and hence it is classified as a non-essential amino acid. It is most frequently synthesized through the transamination of oxaloacetate, in humans. Aspartate is also a by-product of the urea cycle. CAS No. 1115-63-5 Quantity Provided: 25 gm per pack Molecular Formula: C4H6NO4K Molecular Weight: 171.19 Soluble in waterL-Aspartic acid is widely used in chemical and biological sectors. Aspartic acid is increasingly being used in biodegradable superabsorbent polymers (SAP). It is also employed in the fertilizer industry, where polyaspartate improves water retention and nitrogen uptake. Aspartic acid is an endogenous NMDA receptor agonist. It is also a principal neurotransmitter for fast synaptic excitation.
