DL-Histidine is widely used in the pharmaceutical industry as a component in infusion solutions and dietary supplements, particularly for patients with metabolic disorders or those requiring amino acid supplementation. It plays a crucial role in protein synthesis and is essential for tissue repair and growth. In the field of biochemistry, DL-Histidine is utilized as a buffer agent in various enzymatic reactions and protein studies due to its ability to maintain pH stability. Additionally, it is employed in the production of cosmetics and skincare products, where it helps to improve skin hydration and elasticity. In agriculture, DL-Histidine is sometimes added to animal feed to enhance growth and overall health in livestock. Its chelating properties also make it useful in certain industrial processes, such as metal ion stabilization and removal.
