Finally, the use of l-[2-2H1]alanine as a substrate gave a primary deuterium isotope effect (DV = 1.3). All of these results are consistent with the first mechanism in which the formation and acylation of a carbanion precedes the decarboxylation step. The same mechanism has been shown to...
Reaction dynamics of chlorine atom with methane: Dual-level ab initio analytic potential energy surface and isotope effects An analytic potential energy surface for theCl+CH4HCl+CH3reaction inC3Vsymmetry has been obtained by fitting to 1136 energy points from a dual-level MP2/SA... HG Yu,G Ny...
To determine de novo lipogenesis, deuterated water (D2O) (atom 99%, Cambridge Isotope Laboratory) was added to the media to reach an enrichment of 2.5%. The percentage contribution of newly made FA was calculated as total 2H-labeled FA/(2H-labeled body water × n) × 100 (n...
C12FDG added in fresh culture medium and incubated for 2 h. Ten min prior to analysis, 2 μg/mL Hoechst dye was added. An IN Cell Analyzer 6000 was used to quantitate total number of viable cells (Hoechst+) and the number of senescent cells (C12FDG+). All samples ...
neutron radiation, to activate isotope Si3 transmuted acceptor impurity P3l doping impurity. 后期处理:800-850C退火1h左右,以消除辐照造成的损伤; 再放置一段时间(约2个月)以降低放射性。Ge70→Ga71 Post process: in 800-850C annealing around 1h eliminates the damage caused by radiation. ...
The extraction, purification, and quantification of anandamide (AEA), 2-arachydonoylglycerol (2-AG), arachidonic acid (AA), oleoylethanolamide (OEA), and palmitoylethanolamide (PEA) in mouse liver tissue were performed by stable isotope dilution liquid chromatography/tandem mass spectrometry (LC...
I knew nothing about theC3and C4 pathways until recently when I was trying to understand why the C13/C12 isotope ratios for fossil carbon where different than for atmospheric carbon (thus allowing the identification of fossil carbon on theatmosphere). The reason is that while C12 and C13 are ...
