Product Detail

D - Phenylalanine is an enantiomer of phenylalanine and holds significant importance and extensive applications in multiple fields such as biochemistry, pharmaceuticals, and food.

Chemically, D - Phenylalanine has a molecular formula of C9H11NO2 and a molecular weight of 165.19. Its molecular core comprises a benzene ring and an alanine side chain structure. The benzene ring endows it with unique aromatic characteristics, which not only confer special reactivity in chemical reactions but also have a profound impact on its physiological functions and sensory properties. The different spatial configuration from L - Phenylalanine dictates that it follows distinct patterns when interacting with biomolecules such as enzymes and receptors, thus initiating different metabolic pathways and exerting diverse biological effects.

Physically, D - Phenylalanine typically appears as white crystals or crystalline powder, either tasteless or with a slightly bitter taste. It has limited solubility in water, approximately 3 grams per 100 milliliters at 25 °C. However, in acidic or alkaline solutions, its solubility increases significantly due to the solubilizing effect of acids and bases. Its melting point ranges from 270 to 275 °C, exhibiting a certain degree of thermal stability. This property ensures that its structure remains relatively stable under some industrial processes involving heat treatment and in the internal environment of living organisms, enabling it to function properly.

In terms of biosynthesis and metabolic pathways, the production of D - Phenylalanine in nature is rather complex. Certain microorganisms can synthesize D - Phenylalanine through a series of precisely regulated biochemical reactions, using simple carbon sources, nitrogen sources, and aromatic precursors as raw materials with their specific enzyme systems. In higher organisms, its metabolism is related to yet different from that of L - Phenylalanine. Although it is not a regular component of proteins, it can participate in the formation of some secondary metabolites. For example, it serves as a raw material in the synthesis prelude of specific neurotransmitters or helps generate compounds with special defense functions in some plant secondary metabolic pathways.

The pharmaceutical field is where D - Phenylalanine truly shines. On the one hand, it is a crucial intermediate in the synthesis of a variety of drugs. For instance, in the synthesis of certain drugs for treating Parkinson's disease, D - Phenylalanine is indispensable. It endows the drugs with precise structure and activity, allowing them to precisely target diseased sites, regulate neurotransmitter imbalances, and relieve symptoms such as tremors and slow movement in patients. On the other hand, D - Phenylalanine itself and its derivatives exhibit certain pharmacological activities. Research has found that it has potential efficacy in relieving chronic pain, perhaps by interfering with key nodes in the pain signal transduction pathway, reducing the perception and transmission of pain stimuli by the nervous system, bringing hope to patients suffering from long-term pain.

The food industry also has a high regard for D - Phenylalanine. As a food additive, it mainly plays dual roles as a nutritional fortifier and a flavor modifier. In infant formula foods, special medical foods, and other products, the appropriate addition of D - Phenylalanine can ensure that specific populations obtain sufficient amino acid nutrition to support normal body development and function maintenance. In daily food categories such as beverages and baked goods, it can subtly modify the flavor. The unique aroma originating from the benzene ring can enhance the layering of the product's aroma, mask some undesirable off-flavors, and optimize consumers' taste experience.

In the chemical synthesis field, the chiral structure of D - Phenylalanine becomes a powerful tool for asymmetric synthesis. By virtue of its chiral induction effect, chemists can use it as a starting material or an auxiliary to precisely synthesize a large number of optically active compounds that widely permeate industries such as pharmaceuticals, pesticides, and fine chemical materials. For example, in the synthesis of anticancer drugs, the introduction of a chiral center using D - Phenylalanine enables the drug molecule to precisely fit the tumor cell target, enhancing the treatment effect. In the development of new pesticides, it helps construct active ingredients that target the physiological mechanisms of specific pests, ensuring crop yield while minimizing the impact on the environment and non-target organisms.

However, the application of D - Phenylalanine needs to be carefully controlled. In the pharmaceutical sector, excessive intake may disrupt the delicate balance of neurotransmitters in the body, triggering adverse reactions such as anxiety and insomnia, especially for people with more sensitive nervous systems, who require precise dose adjustment. In the food field, although it has been widely recognized as an additive, its usage must strictly adhere to national standards to prevent unknown health risks due to overuse. At the same time, consideration should be given to possible special reactions of different populations, such as those with allergic constitutions.
