D-Arginine (CAS 157-06-2)<\/strong> is the D-isomer of arginine, a conditionally non-essential amino acid. While L-arginine is the more commonly discussed form in nutritional supplements, D-arginine serves distinct biological functions and research applications. This compound is also known by its systematic name D(-)-Arginine and represents the mirror image of L-arginine at the alpha carbon position.<\/p>\n\n\n\n

The molecular formula of D-Arginine is C\u2086H\u2081\u2084N\u2084O\u2082 with a molecular weight of 174.20 g\/mol. It appears as a white crystalline powder and is soluble in water. As a D-amino acid, D-arginine is not incorporated into proteins during translation, but it plays important roles in various biochemical processes and pharmaceutical applications.<\/p>\n\n\n\n

What Are the Benefits?<\/h2>\n\n\n\n

Nitric Oxide Synthesis<\/h3>\n\n\n\n

D-Arginine can react with hydrogen peroxide to produce nitric oxide through non-enzymatic synthesis. This property makes it valuable in research settings studying nitric oxide pathways, which are crucial for cardiovascular health, immune function, and cellular signaling.<\/p>\n\n\n\n

Antimicrobial Properties<\/h3>\n\n\n\n

Research has demonstrated that D-arginine exhibits antimicrobial effects against certain bacteria by inhibiting peptide synthesis. Unlike L-arginine, the D-form cannot be metabolized by standard bacterial enzymatic pathways, giving it unique antimicrobial potential.<\/p>\n\n\n\n

Pharmaceutical Applications<\/h3>\n\n\n\n

The derivative 1-deamino-8-D-arginine vasopressin (desmopressin), synthesized from D-arginine, is clinically significant for managing hemophilia and von Willebrand’s disease. This highlights the importance of D-arginine as a pharmaceutical intermediate.<\/p>\n\n\n\n

Arginine Decarboxylase Inhibitor<\/h3>\n\n\n\n

D-Arginine functions as an EC 4.1.1.19 (arginine decarboxylase) inhibitor, making it useful in biochemical research to study arginine metabolism and enzyme pathways.<\/p>\n\n\n\n

What Are the Uses?<\/h2>\n\n\n\n

Pharmaceutical Intermediate:<\/strong> D-Arginine serves as a crucial building block in synthesizing various pharmaceutical compounds, particularly vasopressin analogs and other peptide-based therapeutics.<\/p>\n\n\n\n

Biochemical Research:<\/strong> Researchers utilize D-arginine to study amino acid metabolism, enzyme inhibition, and nitric oxide synthesis pathways. Its distinct stereochemistry allows for controlled experiments in biochemical studies.<\/p>\n\n\n\n

Nutritional Supplement Research:<\/strong> While L-arginine dominates the supplement market, D-arginine is studied for its unique metabolic properties and potential applications where L-arginine cannot be used.<\/p>\n\n\n\n

Synth\u00e8se chimique :<\/strong> In organic chemistry, D-arginine acts as a chiral building block for synthesizing peptides and other chiral compounds.<\/p>\n\n\n\n

S\u00e9curit\u00e9 et manipulation<\/h2>\n\n\n\n

General Safety:<\/strong> D-Arginine is generally regarded as safe when handled appropriately. However, standard laboratory safety precautions should be observed:<\/p>\n\n\n\n

    \n
  • Use personal protective equipment (PPE) including gloves and safety goggles<\/li>\n
  • Avoid inhalation of dust or particles<\/li>\n
  • Store in a cool, dry place away from incompatible materials<\/li>\n<\/ul>\n\n\n\n

    Storage Conditions:<\/strong> Store D-Arginine at room temperature (15-25\u00b0C) in a tightly sealed container protected from moisture and light. Proper storage ensures stability and maintains product quality.<\/p>\n\n\n\n

    Statut r\u00e9glementaire :<\/strong> D-Arginine is available for research and pharmaceutical applications. For specific regulatory questions, consult relevant authorities in your jurisdiction.<\/p>\n\n\n\n

    Frequently Asked Questions<\/h2>\n\n\n\n

    What is the difference between D-Arginine and L-Arginine?<\/strong>
    D-Arginine and L-Arginine are stereoisomers (mirror images) of each other. L-Arginine is the biologically active form used by the body for protein synthesis and nitric oxide production. D-Arginine has different biological activities and is primarily used in research and pharmaceutical applications.<\/p>\n\n\n\n

    Can D-Arginine be used in supplements?<\/strong>
    Most commercial supplements contain L-Arginine. D-Arginine is primarily used in research and pharmaceutical manufacturing rather than direct consumer supplementation.<\/p>\n\n\n\n

    Is D-Arginine safe?<\/strong>
    When handled following standard laboratory safety protocols, D-Arginine is considered safe for research and industrial applications.<\/p>\n\n\n\n

    What is the CAS number for D-Arginine?<\/strong>
    D-Arginine has the CAS number 157-06-2, which uniquely identifies this specific chemical compound.<\/p>\n\n\n\n
