We have developed an efficient stereospecific enzymatic synthesis of L-[15N]-valine, L-[15N]-leucine, L-[15N]-norvaline, L-[15N]-norleucine and L-[15N]-isoleucine from the corresponding α-keto acids by coupling the reactions catalysed by leucine deh

In the infrared multiphoton dissociation (IRMPD) of (CH 3 ) 2 NH (DMA) and (CH 3 ) 3 N (TMA) molecules, in the medium pressure domain (10 Torr), the CH 3 N and NH bonds can be easily broken to produce CH 3 and other free radicals. In TMA and DM
