Medchemexpress LLC L-Valine-13C5,15N | 202407-30-5 | 123.10 | 5 MG
L-Valine-13C5,15N is a 13C- and 15N-labeled L-Valine, a nonlinear semiorganic material. It causes lipid peroxidation, accumulates malondialdehyde (MDA), and inhibits cyanobacteria. It also inhibits multidrug-resistant bacteria by activating the PI3K/Akt pathway and inhibiting arginase. This compound serves as a tracer and an internal standard for quantitative analysis via NMR, GC-MS, or LC-MS, utilizing stable heavy isotopes for drug development and pharmacokinetic studies.
