Gas Chromatographic Determination of Mura.mic Acid, Glucosamine, Mannosamine, and Galactosamine in Soils

Muramic acid, glucosamine, mannosamine and galactosamine in soils may be useful for elucidating the microbial origin of soil organic nitrogen. Therefore, a method was developed to determine the aldononitrile acetate derivatives of the four amino sugars simultaneously in the 6 M HCl hydrolysates of soil samples by means of high resolution gas li uid chromatography. This method was sensitive enou...

Chromatographic separation of glycated nucleotides.

A high-performance liquid chromatographic method for the separation of nucleotide glycation reaction product(s) has been developed. The product(s) arising during in vitro glycation of a nucleotide (AMP, GMP or CMP) with a reducing sugar (ribose or glucose) were clearly resolved from the non-glycated constituents of the reaction mixture. The peak(s) of the glycated product(s) increased when an a...

Chromatographic Separation of the Diastereoisomers

Reduction of folic acid to the tetrahydro level introduces a second asymmetrical center into the molecule at carbon atom 6.1 The resulting tetrahydrofolate, and subsequent derivatives, prepared chemically consist of dl mixtures that are only 50% active in biological reactions. The need for fully reactive isomers of reduced folates led to the enzymatic synthesis of tetrahydrofolate from 7, %dihy...
