Overview
DL-Valine is a racemic mixture of the essential amino acid valine, meaning it contains equal parts of the D- and L-enantiomers. It plays a crucial role in protein synthesis and metabolic processes in humans and animals. Unlike L-valine, which is the naturally occurring form, DL-valine is synthesized and used primarily in industrial and research applications. DL-Valine is widely utilized in pharmaceuticals, where it serves as a building block for drugs and supplements. It is also used in food additives to enhance nutritional value and in biochemical research to study amino acid metabolism and protein structure.
Physical and Chemical Properties
DL-Valine appears as a white crystalline powder with a molecular weight of 117.15 g/mol. It has a melting point of approximately 315°C, at which it decomposes rather than melts. The compound is soluble in water and slightly soluble in ethanol, making it versatile for various applications. The racemic nature of DL-valine means it does not exhibit optical activity, unlike its enantiomerically pure counterparts. This property is often exploited in research settings where the specific stereochemistry of valine is not a critical factor. The compound is stable under normal storage conditions but should be kept away from moisture and direct sunlight to prevent degradation.
Main Applications
In the pharmaceutical industry, DL-valine is used as an intermediate in the synthesis of drugs and dietary supplements. Its role in protein synthesis makes it valuable for formulations aimed at improving muscle growth and recovery. Additionally, it is used in parenteral nutrition solutions for patients unable to consume food orally. The food industry incorporates DL-valine into products as a nutritional enhancer, particularly in sports nutrition and animal feed. In biochemical research, DL-valine is employed to study enzyme kinetics, metabolic pathways, and protein folding mechanisms, providing insights into fundamental biological processes.
Safety and Storage
DL-Valine is generally considered safe when handled properly, but precautions should be taken to avoid inhalation, ingestion, or direct contact with skin and eyes. Personal protective equipment, such as gloves and safety goggles, is recommended when working with the compound. Storage conditions for DL-valine include keeping it in a cool, dry place, away from direct sunlight and moisture. Properly sealed containers are essential to maintain the compound's stability and prevent contamination. In case of exposure, rinse affected areas with plenty of water and seek medical advice if necessary.
B2B Procurement Guide
When procuring DL-valine, B2B buyers should prioritize suppliers who provide detailed certificates of analysis (CoA) to ensure product purity and quality. Compliance with relevant regulatory standards, such as USP, EP, or BP, is also a key consideration. Price ranges for DL-valine typically fall between $20 and $50 per kilogram, depending on purity and order volume. Bulk purchases often attract discounts, making it cost-effective for large-scale applications. Buyers should also consider logistics, including packaging and shipping conditions, to ensure the product arrives in optimal condition.
