L-aspartic acid is the L-enantiomer of aspartic acid and the the enantiomer of D-aspartic acid. It is one of the 20 amino acids used in protein synthesis. It is a non-essential amino acid for the human body because it can be synthesized in the body.

Properties of L-Aspartic Acid Powder

  • An organic compound with the chemical formula C4H7NO4.
  • White crystal or crystalline powder, slightly sour taste.
  • Soluble in boiling water, slightly soluble in water at 25℃, easily soluble in dilute acid and sodium hydroxide solution, insoluble in ethanol and ether.
  • It decomposes when heated to 270℃.
  • Its specific rotation is related to the dissolved solvent. It is dextrorotatory in acid solution, levorotatory in alkaline solution, and dextrorotatory in aqueous solution.
    1. As electrolyte supplement, it is used for amino acid infusion, potassium, calcium and other inorganic ion supplements.
    2. It can be used as ammonia detoxifier, liver function enhancerand other pharmaceutical products.
    3. Fatigue recovery agent in sports drinks.
    4. Used as biochemical reagents, culture medium and organic synthesis intermediates.
    5. In food processing, it is used as nutritional supplement, flavoring agent, freshener, low-calorie and high-sweetening agent. It is used as a food additive in various refreshing beverages.
    6. L-aspartic acid is often used as a chiral substrate for diastereomeric alkylation reactions, and can be used as a chiral source to synthesize other chiral compounds, etc. For example, after the use of cuprous iodide, sodium borohydride, multifunctional oxazine heterocyclic compounds can be obtained, which can further generate quinoline compounds.
    7. As an amino acid, L-aspartic acid, like other amino acids, can also generate amide compounds.
    8. L-aspartic acid can be used as the parent to realize the synthesis of cyclic lactam.
    9. Synthesis of β-amino acids. L-aspartic acid can generate β-amino acid or amino acid ester after amino protection, alkylation and other steps. This reaction achieves the conversion from natural amino acids to unnatural amino acids.
    10. L-aspartic acidwas shown to be a suitable prodrug for colon-specific drug delivery.
    11. In addition, L-aspartic acid molecule contains two carboxyl groups and one amino group. So it can be used as a polydentate ligand to coordinate with metal ions or form lactone compounds by itself.

    Aspartic acid is an alpha-amino acid. L-Aspartic acid can be directly incorporated into proteins. D-aspartic acid has a more limited biological effect. DL-aspartic acid, known as a racemic mixture.

    Aspartic acid is present in all organisms, from bacteria to plants to animals. Foods high in aspartate include oysters, lunch meat, sausage meat, game, sprouted seeds, oatmeal, avocado, asparagus, tender sugar cane, and beet molasses.

    It is classified as an acidic, charged aliphatic amino acid. In humans, aspartic acid is a non-essential amino acid extracted from glutamic acid by enzymes that use vitamin B6.

    Magnesium and zinc may be natural inhibitors of some of the effects of aspartate. When chemically coupled to the amino acid D-phenylalanine, aspartic acid is part of the natural sweetener aspartame.
