Cysteine residues in polypeptides are not easily identified during automated N-terminal sequence analysis. Reaction of cysteine side chains with 4-vinylpyridine and identification as the pyridylethylated phenylthiohydantion derivative (PE-PTH-Cys) were proposed. However, after this reaction a desalting step is necessary. If

The experimental FT-IR (4000-400 cm(-1)) and FT-Raman (3500-100 cm(-1)) spectra of 4-Methylmorpholine were recorded. The observed bands were interpreted with the aid of normal coordinate analysis and force field calculations based on density functional theory (DFT) using B3LYP functional theory

Pretreatment of cellulose with an industrial cellulosic solvent, N-methylmorpholine-N-oxide, showed promising results in increasing the rate of subsequent enzymatic hydrolysis. Cotton linter was used as high crystalline cellulose. After the pretreatment, the cellulose was almost completely hydrolyzed in less than

During the analysis of "seized samples", suspected of containing 4-methylmethcathinone (mephedrone) and N-ethylcathinone (ethcathinone) additional compounds were observed in the GCMS chromatogram. These compounds were suspected to be the corresponding phenylacetone isomers of mephedrone and ethcathinone respectively. These isomers are
