The structure of simple polysaccharides can be determined by acombination of permethylation, hydrolysis,reduction, and in some case enzymatic digestion. Duringpermethylation (also known as exhaustivemethylation) all the free hydroxyl residues are methylated. Uponacid hydrolysis, the glycosidic bonds and themethyl groups attached to anomeric carbons are cleaved while theother methyl groups resist hydrolysis.A trisaccharide of unknown structure is submitted to permethylationfollowed by acid hydrolysis. After thistreatment, you identify three molecules:2,3,4,6 tetramethylglucopyrannose2,3,4 trimethylglucopyrannose2,3,6 trimethylgalactopyrannoseThe numbers indicate the methylated carbons in each of thesemolecules.Additional experiments show the following:- The trisaccharide is reduced by the Fehling’s solution.- The digestion of the trisaccharide by a class of enzymes calledβ-glucosidases result in the complete digestionof the trisaccharide and the release of two molecules of glucoseand one molecule of galactose. A β-glucosidase cleaves a glycosidic bond that is located downstream(on the right) of a glucose unit it a β-configuration.Based on all the information provided, determine the fullsystematic name of this trisaccharide. Provide adetailed justification of your answer.
