- What sugar is the C-5 epimer of d-allose?arrow_forwardWhich of the aldohexoses are epimers of D-allose?arrow_forward1 Draw D- glucose in a Fischer Projection. 2 Draw alpha-D- glucose and in the Hayworth (ring ) structure. 3 Draw the hydrolysis of maltose- the disaccharide composed of alpha D glucose molecules. 4 What is the chemical difference between cellulose and amylose NOTE- please dont explain too much explain to the pointarrow_forward
- How is each compound related to the simple sugar D-erythrose? Is it an enantiomer, a diastereomer, or an identical molecule?arrow_forwardRaffinose is a trisaccharide (C18H32O16) isolated from cottonseed meal. Raffinose doesnot reduce Tollens reagent, and it does not mutarotate. Complete hydrolysis of raffinosegives d-glucose, d-fructose, and d-galactose. When raffinose is treated with invertase,the products are d-fructose and a reducing disaccharide called melibiose. Raffinose isunaffected by treatment with a b@galactosidase, but an a@galactosidase hydrolyzes itto d-galactose and sucrose. When raffinose is treated with dimethyl sulfate and basefollowed by hydrolysis, the products are 2,3,4-tri-O-methylglucose, 1,3,4,6-tetraO-methylfructose, and 2,3,4,6-tetra-O-methylgalactose. Determine the completestructures of raffinose and melibiose, and give a systematic name for melibiose.arrow_forwardGulose is a C3 epimer of Galactose and a C2 epimer of Idose. Modified True or Falsearrow_forward
- Draw the following monosaccharides, using chair conformations for the pyranoses andHaworth projections for the furanoses.(a) a-d-mannopyranose (C2 epimer of glucose)arrow_forwardClassify structure A, B, and C in the figure as being either an enantiomer, diasteromer or epimer of Mannose.arrow_forwardThe anticoagulant heparin is a polysaccharide that contains alternating residues of -D- glucuronic acid-6- sulfate and N-sulfo-D-glucosamine-6sulfate connected by (1 B 4)- glycosidic linkages. Draw a part of heparin that shows one each of the two residues.arrow_forward
- Draw the following monosaccharides, using chair conformations for the pyranoses andHaworth projections for the furanoses. ) b-d-galactopyranose (C4 epimer of glucose)arrow_forwardClassify below pair of compounds as enantiomers, epimers, diastereomers but not epimers, or constitutional isomers of each other. D-allose and L-allosearrow_forwardWhich of the following is the epimer of glucose at C-4? a. mannose b. fructose c. allose d. mannose e. galactosearrow_forward
