The complexity of forest soil carbohydrates as demonstrated by 27 different o-methyl monosaccharides, 10 previously unknown in nature
OGNER, G.
Soil carbohydrates are a mixture of a variety of different polysaccharides, all of unknown structure. They may originate from soil bacteria, fungi and algae, or soil animals. Of the 27 mono- and di-O-methyl monosaccharides detected in a raw humus hydrolyzate, 10 have not been found in nature before. These are 2,3-di-O-methyl-arabinose; 4-O-methyl-rhamnose; 2,6-di-O-methyl-galactose; 2,6,-di-O-methyl-glucose; 2,4-di-O-methyl-glucose; 2,4-di-O-methyl-mannose; 3,6-di-O-methyl-glucose or mannose; 6-O-methyl-mannose; 2-O-methyl-mannose; and 2-O-methyl-glucose.
