Uses of L-Aspartic Acid
L-Aspartic Acid is widely used. In medicine, it can be widely used as a supplementary fatigue recovery agent for inorganic ions such as potassium and calcium, ammonia antidote and amino acid infusion, and other medicines. Due to the special sweetness of L-aspartic Acid, it can be used as a food additive. L-aspartic Acid can be made into the poly aspartic acid polymer, used as a scale inhibitor, thickener, surfactant, etc., and can also be used as a non-polluting pesticide.
Applications in the pharmaceutical industry
L-Aspartic Acid is one of the twenty basic amino acids that constitute proteins, and it has a wide range of applications in biochemical reagents and clinical medicine. As a non-essential amino acid for the human body, it can regulate the metabolic functions of the brain and nerves. Its L-aspartic Acid (L-Asp) is widely used as an ammonia detoxifier, liver function promoter, fatigue recovery agent, and other medical supplies and additives for various refreshing drinks. Its racemic DL-aspartic Acid (DL-Asp) can be used to synthesize DL-aspartic acid potassium magnesium salt for the treatment of arrhythmia, tachycardia, heart failure, myocardial infarction, angina pectoris, hepatitis, and liver disease. Sclerosis and other diseases.
Potassium magnesium aspartate (PMA) has a strong affinity for cells, and as a chelating agent, it separates slowly after combining with metal ions. When potassium and magnesium are deficient, PMA can be used as a carrier to promote potassium and magnesium ions to enter cells so as to better exert their biological effects easily. In addition, PMA can make arrhythmia disappear or significantly reduce, and its total effective rate is as high as 94%. DL-aspartic Acid can also be used as a raw material for synthetic polypeptides, and its amino acid substitution derivative (NMDLA) can be used as a drug for treating neurological diseases and brain diseases.
Applications in Agriculture
Polyaspartic acid derivatives can easily enter the roots of plants in the soil and can absorb and enrich the elements useful to plants in the soil around the roots, such as N, P, K, Ca, Mg, S, №, Cu, and Fe, etc., to promote plant growth. It is applicable to various soils, and besides direct application, it can also be used for coating plant seeds, which has the function of improving the germination rate. Due to the good degradability of polyaspartic Acid, its use can not only promote plant growth but also reduce surface water pollution caused by excessive fertilizer application. Therefore, polyaspartic Acid is a new generation of fertilizer synergist that attracts attention. At the same time, because polyaspartic Acid has good insecticidal, sterilizing and dispersing capabilities, polyaspartic Acid is used in pesticides. It can not only protect plants from diseases and insect pests, but also compound with other components of pesticides to make them wet, disperse, solubilize and penetrate on the surface of plants, and give full play to the efficacy of pesticides.
Application in industry
L-aspartic Acid can be prepared as polyaspartic acid derivative (PASP). C． S． Sikes et al. used poly aspartate, polyglutamate, and other amino acid copolymers to inhibit the precipitation of inorganic and organic calcium carbonate. The optimum molecular weight of the copolymer is 3500-10000, and it is biodegradable and can be used as a scale inhibitor for seawater desalination equipment or circulating cooling water. C． S． Sikes et al. also studied the metal-blocking precipitant of hydrophobic amino acids (peptides) containing multiple anions. It has a block structure, a block consisting of 15 aspartic acid units and 8 alanine units, the least effective peptide consists of 5 units, 2 of which are selected from ionic amino acid groups, and 2 The blocks together do not exceed 120 units. The reaction product of poly succinimide and long-chain alkylamine was prepared, which can be used as a surfactant in the cleaning agent.
Applications in other areas
L-Aspartic Acid can also be prepared into various derivatives and used in daily chemicals, such as moisturizing and moisturizing products, shampoo and conditioner, etc. It can also be used as a dispersant in pigments and coatings.
