Oxidation in vivo of the methyl groups of choline, betaine, dimethylthetin, and dimethyl-beta-propiothetin.
It has recently been demonstrated in this laboratory (l-3) that “biologically labile” methyl groups can be oxidized to CO2 in the rat. This has been established by feeding methionine containing radioactive carbon in the methyl group and demonstrating the presence of radioactive CO2 in the expired air. In the present communication a comparison is made of the rates of oxidation of methyl groups a...
متن کاملDimethyl sulfide for 3-carboaldehyde pyridine displacement in a platinum(II) complex: Donor number effect
The therrmodynamic parameters and equilibrium constant of displacement of dimethy sulfide by 3-carboaldehyde pyridine as N-donor ligand in cis-[Pt(4-MeC6H4)2(SMe2)2] complex have been measured using UV vis spectroscopy in acetone, dichloromethane and benzene at various temperatures (T=15-20 °C) and compared with previous my reported about similar reaction. ΔHo (KJ.mol-1) of the mentioned reacti...
متن کاملDimethyl 2-methyl-1,2-dihydroquinoline-2,4-dicarboxylate
In the crystal of the title compound, C(14)H(15)NO(4), pairs of inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(10) dimers. These dimers are further connected via inter-molecular C-H⋯O hydrogen bonds, forming a three-dimensional network. The heterocyclic ring adopts a twisted conformation.
متن کاملCoupled methyl groups in dimethyl sulphide
Low field methyl tunnelling spectra of dimethyl sulphide have been measured using field cycling NMR and indicate the existence of two distinct methyl groups with tunnel. frequencies of 100kHz and 750kHz. Spectra show a significant broadening of the Larmor peak at those fields at which the Larmor and tunnel frequencies are equal. These are resonances between the rotational and spin dynamics of t...
متن کاملA Methyl Substituted Thiophenic-TTF Donor and its Salts
-methyldithiophene-tetrathiafulvalene (-mDT-TTF), the first alkyl substituted thiophenic-TTF electronic donor, as well as some of its charge transfer salts are reported. The crystal structure of -mDT-TTF is composed of molecular stacks aligned parallel to each other. Its cyclic voltammetry shows higher electron donor ability than the unsubstituted analogue -DT-TTF. This material has been em...
