Beta-alanine 15N is primarily used in research and scientific studies as a stable isotope-labeled compound. It serves as a tracer in metabolic studies, allowing researchers to track and analyze the pathways and mechanisms of beta-alanine metabolism in biological systems. This isotope-labeled form is particularly valuable in NMR spectroscopy and mass spectrometry, where it helps in identifying and quantifying metabolic intermediates and products. Additionally, it aids in understanding the role of beta-alanine in carnosine synthesis, which is crucial for muscle performance and buffering capacity. Its application extends to nutritional and physiological research, providing insights into dietary supplements and their impact on athletic performance and muscle health.
