💡 Commercial Applications
D-glutamic acid, a nonproteinogenic amino acid, has a variety of commercial and industrial applications. It is commonly used as a flavor enhancer in the food industry, particularly in savory products like soups, sauces, and seasonings. D-glutamic acid is also utilized in the production of biodegradable polymers and as a component in cosmetic formulations, due to its ability to improve skin hydration and elasticity.
In addition to its commercial and industrial uses, D-glutamic acid is also employed in pharmaceutical and medical applications. This amino acid has been found to have neuroprotective effects, making it a potential candidate for drugs targeting neurodegenerative diseases such as Alzheimer’s and Parkinson’s. D-glutamic acid is also used in the synthesis of drugs like anti-inflammatory agents and antibiotics, contributing to the development of new medications for various health conditions.
⚗️ Chemical & Physical Properties
D-glutamic acid is a white, crystalline solid with a slight odor. Its appearance is often described as powdery or granular, and it is typically odorless when pure.
The molar mass of D-glutamic acid is approximately 147.13 g/mol, with a density of 1.538 g/cm³. This places it between the molar mass and density of common food items such as table sugar and salt, making it a moderately heavy and dense substance compared to these everyday products.
D-glutamic acid has a melting point of approximately 220°C and a boiling point of around 245°C. These values are significantly higher than those of common food items such as butter or chocolate, which have lower melting and boiling points in comparison.
D-glutamic acid is highly soluble in water, forming a clear and colorless solution. Its viscosity is relatively low, making it easy to dissolve and mix with other substances. This solubility and viscosity are different from many common food items, which may have varying degrees of solubility and viscosity in water.
🏭 Production & Procurement
D-glutamic acid is typically produced through microbial fermentation, most commonly using strains of bacteria such as Corynebacterium glutamicum or Bacillus subtilis. These microorganisms are cultivated in bioreactors with a carbon source and other essential nutrients, leading to the production of D-glutamic acid through metabolic processes.
The procurement of D-glutamic acid can be done through chemical synthesis, enzymatic conversion, or extraction from natural sources such as gluten or hydrolyzed proteins. Once produced, D-glutamic acid can be purified and transported in either liquid or powder form, depending on the end use. Transportation methods may include shipping in bulk containers or smaller packaging for distribution to various industries.
Due to the widespread applications of D-glutamic acid in food, pharmaceuticals, and other industries, it is in demand globally. Suppliers of D-glutamic acid may be found in various regions around the world, with large-scale producers able to fulfill orders for both commercial and research purposes. The transportation of D-glutamic acid may involve coordination between suppliers, distributors, and end users to ensure timely delivery and quality product.
