Valine is widely used in the pharmaceutical industry as a key component in intravenous solutions for patients who cannot consume food orally, aiding in muscle metabolism and tissue repair. It is also a crucial ingredient in sports nutrition supplements, promoting muscle growth, endurance, and recovery after intense physical activity. In the food industry, valine is added to fortified foods and beverages to enhance nutritional value, particularly in products targeting athletes or individuals with protein deficiencies. Additionally, it plays a role in animal feed formulations to improve livestock growth and overall health. Its application in biotechnology includes its use as a building block in peptide synthesis and protein engineering research.
