    L-Valine Analysis Service

      L-Valine is an essential amino acid that must be obtained through diet as the human body cannot synthesize it. It plays a crucial role in protein synthesis, tissue repair, and energy metabolism, particularly in muscle metabolism and immune function. During periods of stress and exercise, the demand for L-valine increases, making it vital to maintain adequate levels for overall health. The metabolic pathway of L-valine involves its conversion to α-ketoisovaleric acid, which then enters the citric acid cycle for energy production. Additionally, L-valine's metabolite, β-hydroxy-β-methylbutyrate (HMB), is an important metabolic regulator that helps reduce protein breakdown and promotes muscle growth and repair. Thus, L-valine metabolism is essential for maintaining muscle mass and overall metabolic health.


      Changes in L-valine levels can indicate various physiological and pathological states, such as liver diseases, metabolic syndrome, and neurodegenerative diseases. Accurate analysis of L-valine levels and their fluctuations in these conditions aids in understanding its role in health and disease, providing a scientific basis for clinical diagnosis and treatment. Therefore, precise analysis of L-valine is of significant importance in biomedical research and clinical diagnostics.

      MtoZ Biolabs utilizes liquid chromatography-tandem mass spectrometry (LC-MS/MS) to conduct detailed quantitative and qualitative analyses of L-valine and its metabolites. This advanced method integrates LC's rapid separation capabilities with the high detection sensitivity of MS/MS, facilitating the precise measurement of L-valine in complex biological matrices.
