Amino compounds in lipopolysaccharides.
In a previous report (1) the isolation, toxicity and some chemical data concerning the lipopolysaccharide endotoxin of Neisseria gonorrhoeae was described. The present investigation includes the following: (a) an improved modification of lipopolysaccharide phosphoric acid ester preparation; (b) hydrolysis of lipopolysaccharide phosphoric acid ester and removal of fatty acids; (c) separation of ...
متن کاملThe estimation of fatty acids of intermediate chain length by partition chromatography.
In 1942 Smith (1) demonstrated that the silica gel partition chromatogram, first developed by Martin and Synge (2), would separate a mixture of formic, acetic, propionic, n-butyric, and n-valeric acids in chloroform-l per cent butanol into its component acids. In 1945 Ramsey and Patterson (3) confirmed this work and presented a partition chromatographic method for the qualitative separation and...
متن کاملGas-liquid partition chromatography; the separation and micro-estimation of volatile fatty acids from formic acid to dodecanoic acid.
Industry has long used charcoal or other solid absorbents in columns for cleaning gas streams or for solvent recovery, and more recently Turner (1943), Claesson (1946), Glueckauf, Barker & Kitt (1949), Phillips (1949) and Turkel'taub (1950) have used charcoal in gas chromatograms for the analysis of hydrocarbons and esters. Gas-liquid scrubbing columns have been used in industry for many years ...
متن کاملApplication of Graph Theory: Relationship of Topological Indices with the Partition Coefficient (logP) of the Monocarboxylic Acids
It is well known that the chemical behavior of a compound is dependent upon the structure of itsmolecules. Quantitative structure – activity relationship (QSAR) studies and quantitative structure –property relationship (QSPR) studies are active areas of chemical research that focus on the nature ofthis dependency. Topological indices are the numerical value associated with chemical constitution...
متن کاملEffective Solvent Systems for Separation of PTH-Amino Acids on Polyamide Sheet
Two dimensional thin layer chromatography on polyamide sheets is a useful method for identification of PTH-amino acids which have very close Rf-values. The solvent systems described here are particularly effective and have an edge over other solvent systems used for the separation of PTH-amino acids. The solvent systems provide a clear separation of all PTH-amono acids except lle / Leu in a...
