In medical applications, L-Histidine is utilized in the treatment of rheumatoid arthritis due to its anti-inflammatory properties. Additionally, it serves as a buffering agent in various cosmetic and skincare products, helping to maintain the pH balance and enhance skin hydration. Its role in protein synthesis makes it essential in cell culture media for biotechnological research and development.
