Biosynthesis of carnitine and 4-N-trimethylaminobutyrate from 6-N-trimethyl-lysine.
The conversion of 6-N-[Me-(14)C]trimethyl-lysine into carnitine and 4-N-trimethylaminobutyrate (butyrobetaine) was demonstrated in rats kept on a lysine-deficient diet. After the rats were given [(14)C]trimethyl-lysine for 4 days, a total of 17% of the injected label was recovered as carnitine from carcass and urine extracts. Another 8% of the trimethyl-lysine label was converted into 4-N-trime...
متن کاملBiosynthesis of carnitine and 4-N-trimethylaminobutyrate from lysine.
The conversion of l-[U-(14)C]lysine into carnitine was demonstrated in normal, choline-deficient and lysine-deficient rats. In other experiments in vivo radioactivity from l-[4,5-(3)H]lysine and dl-[6-(14)C]lysine was incorporated into carnitine; however, radioactivity from dl-[1-(14)C]lysine and dl-[2-(14)C]lysine was not incorporated. Administered l-[Me-(14)C]methionine labelled only the 4-N-...
متن کاملN′′-(4-Methoxyphenyl)-N,N,N′-trimethyl-N′-phenylguanidine
In the title compound, C17H21N3O, the C-N bond lengths in the guanidine unit are 1.2889 (19), 1.3682 (19) and 1.408 (2) Å, indicating double- and single-bond character. The N-C-N angles are 115.10 (13), 119.29 (15) and 125.61 (14)°, showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. In the crystal, non-classical C-H⋯O hydrogen bonds between methyl H atoms and meth-oxy ...

The C-N bond lengths in the guanidine unit of the title compound, C16H18N4O2, are 1.298 (2), 1.353 (2) and 1.401 (3) Å, indicating double- and single-bond character. The N-C-N angles are 115.81 (16), 118.90 (18) and 125.16 (18)°, showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. In the crystal, C-H⋯O hydrogen bonds are observed between the methyl- and aromatic-H atoms...

The bond parameters and conformations of the N-H and C=O bonds of the SO(2)-NH-CO-C group in the title compound, C(12)H(17)NO(3)S, anti to each other, are similar to what has been observed in related structures. The benzene ring and the SO(2)-NH-CO-C group make a dihedral angle of 71.2 (1)°. Inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
