DL-Aspartic Acid Potassium Crystalline (CAS No. 14434-35-6): An Overview of Its Properties, Applications, and Recent Research

DL-Aspartic Acid Potassium Crystalline (CAS No. 14434-35-6) is a versatile compound with significant applications in various fields, including pharmaceuticals, nutraceuticals, and biochemical research. This compound is a salt form of aspartic acid, a non-essential amino acid that plays a crucial role in numerous biological processes. In this comprehensive overview, we will delve into the chemical properties, biological functions, and recent advancements in the research and application of DL-Aspartic Acid Potassium Crystalline.

Chemical Properties

DL-Aspartic Acid Potassium Crystalline is a white crystalline powder that is highly soluble in water. Its molecular formula is C₄H₇KNO₄, and it has a molecular weight of 180.20 g/mol. The compound is stable under normal conditions but can decompose at high temperatures. The potassium salt form of aspartic acid provides enhanced solubility and bioavailability compared to the free acid form, making it particularly useful in formulations where high solubility is required.

The crystal structure of DL-Aspartic Acid Potassium Crystalline has been extensively studied using X-ray diffraction techniques. These studies have revealed that the compound forms a well-defined crystal lattice, which contributes to its stability and ease of handling in various applications. The crystalline form also ensures consistent quality and purity, which are critical factors in pharmaceutical and nutraceutical formulations.

Biological Functions

DL-Aspartic Acid Potassium Crystalline plays a vital role in several biological processes due to its involvement in protein synthesis and metabolism. Aspartic acid is one of the 20 standard amino acids used to build proteins. It is involved in the urea cycle, which helps remove ammonia from the body, and it also serves as a precursor for the synthesis of other amino acids such as methionine and threonine.

In addition to its role in protein synthesis, aspartic acid is involved in the production of neurotransmitters such as aspartate and N-methyl-D-aspartate (NMDA). These neurotransmitters are crucial for brain function and are involved in processes such as learning and memory. The potassium salt form of aspartic acid further enhances its biological activity by providing potassium ions, which are essential for maintaining proper nerve function and muscle contraction.

Pharmaceutical Applications

DL-Aspartic Acid Potassium Crystalline has found numerous applications in the pharmaceutical industry due to its unique properties. One of its primary uses is as an excipient in drug formulations. Its high solubility and stability make it an excellent choice for enhancing the bioavailability of poorly soluble drugs. This property is particularly valuable in developing oral formulations where rapid absorption is desired.

The compound is also used as a buffer agent in pharmaceutical solutions to maintain pH stability. Its ability to buffer solutions within a physiological pH range makes it suitable for use in parenteral formulations, where maintaining pH balance is critical for patient safety.

In recent years, there has been growing interest in the use of DL-Aspartic Acid Potassium Crystalline as a potential therapeutic agent. Studies have shown that it may have neuroprotective effects by reducing oxidative stress and inflammation in neuronal cells. This property has led to its investigation as a potential treatment for neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease.

Nutraceutical Applications

Beyond its pharmaceutical uses, DL-Aspartic Acid Potassium Crystalline has gained attention in the nutraceutical industry due to its potential health benefits. As an essential component of proteins, it supports muscle growth and repair, making it a popular ingredient in sports nutrition supplements.
