What would be the probable function of this disaccharide, structural or storage?Match the following structural composition with the corresponding polysaccharide Linear homoglycan of glucose connected by α1-4 linkages Branched glycan formed by alternating units of D-galactose and L-galactose Linear sulfated chains of alternating β-D-galactopyranose and 3,6-anhydro- α-galactopyranosyl units Poly-β-Dmannopyranosyluronic acid and/or Poly-α-L-gulopyranosyluronic acid Repeating Poly-D-galacturonic acid residues…Draw the structural formula for ⍺-D-glucosyl-(1 6)-D-mannosamine, does the compound have a reducing sugar? If yes, circle the part of this structure that makes the compound a reducing sugar.
- s N-acetyl-β-D-glucosamine a reducing sugar? What about D-gluconate? Is the disaccharide GlcN(α1→1α)Glc a reducing sugar?Draw the structure of: a. 1-palmitoleyl-2-linolenyl-3-stearyltriglyceride. b. 1-linolenyl-2-arachidyl-3-phosphatidylserine.Draw the structural formula for α-D-glucosyl-(1→6)-D-mannosamine,and circle the part of this structure that makes the compound a reducing sugar.
- write the structure of the following disaccharides ex: Beta- D- Galactopyranosyl- alpha-D-glucoseWhich of the following is the correct systematic name of the disaccharide shown? α-D-glucopyranosyl-(1→3)-β-D-galactopyranose α-D-gulopyranosyl-(1→4)-β-D-glucopyranose α-D-gulopyranosyl-(1→4)-β-D-galactopyranose α-D-glucopyranosyl-(1→3)-β-D-glucopyranoseWhen a certain trisaccharide is completely methylated (i.e. all of the free OH groups have been converted to OCH3 groups) and then hydrolyzed (i.e. all of the glycosidic linkages have been broken) equal molar amounts of 2,3,4,6-tetra-O-methyl-D-galactose, 2,3,4-tri-O-methyl-D- mannose, and 1,2,4,6-tetra-O-methyl-D-glucose are obtained. When this same trisaccaride is treated with beta-galactosidase ( an enzyme that hydrolyzes the indicated glycosidic bond indicted by it's name) it yields D- galactose and a disaccharide. Treatment of the resulting disaccharride with alpha- mannosidase yields D-mannose and D-glucose. Draw the structure of the beta anomer of the original trisaccharide.
- An unknown trisaccharide was treated with dimethyl sulfate which adds a methyl group to every free OH group. It was then subjected to acid hydrolysis (to break glycoside bonds).
