| Popis: | Mesquite gum was subjected to the Smith procedure involving periodate oxidation, reduction, and mild hydrolysis. The main D-galactose chain was fragmented to a greater extent than expected. The quantity of glycerol formed indicated the presence of a considerable number of 1 → 6 linkages while the formation of threitol showed the presence of 1 → 4 linkages. Several small oligosaccharides terminated by a glycerol residue were isolated together with an oligosaccharide of D.P. 30. Further periodate oxidation of the latter gave a product with D.P. 24 which was in turn oxidized to a compound consisting largely of D-galactose and glycerol. Reduction of the acidic fraction gave mainly 2-O-methyl-D-erythritol. |
