Concept explainers
Interpretation:
Structure for the pyranose and furanose forms of the D-ribose are to be drawn and a distinction between methyl ribopyranoside and methyl ribofuranoside molecules using periodate oxidation is to be shown.
Concept Introduction:
▸ The pyranoses are six-membered monosaccharide ring structures. The furanoses are five-membered monosaccharide ring structures.
▸ The Fischer projection and Haworth’s formulas are different ways of representing the

- Draw the products from Killiani-Fischer reaction of D-ribose and L-Xylose.arrow_forwardWrite down the reactions: D-Glucose + HNO3 →arrow_forwardResearchers analysed a glycopeptide (a peptide carrying one or several oligosaccharide groups) and determined both the sequence of the peptide and the sequence of the sugar molecule. The latter was identified as a diholoside coupled to the peptide by an osidic bond. The systematic name of this sugar is: B-D-glucopyranosyl-(1→4)-ß-D-galactopyranose. : Represent the chemical formula of this diholoside in a way that all oses are Question 1 represented according to the Haworth convention. Apart from the furane and/or pyrane cycles all atoms of this molecule must be given.arrow_forward
- Kindly answer question i & iiarrow_forwardDraw the product resulting from the Molisch reaction with D-xylose.arrow_forwardIdentify the organic functional group and reaction type for the following reaction. The reactant is a(n) - carboxylic acid hexose - Aldohexose - aldotetrose -deoxyhexose -carboxylic acid tetrose - ketohexose The product is a(n) - carboxylic acid tetrose - aldotetrose -alcohol hexose -aldohexose -carboxylic acid hexose - alcohol tetrose The reaction type is - hemiacetal formation -hydrolysis -oxidation( Benedict’s) -acetal formation -reduction( hydrogenation) - mutarotationarrow_forward
- Draw the product when the following tripeptide is treated with each reagent.a. Please refer image b. H3O+c. C6H5NCSd. CH3OH, H+arrow_forwardDraw the structures of an aldopentose and a ketohexose.arrow_forwardA tripeptide undergoes complete hydrolysis and the resulting mixture contains only phenylalanine and glycine. Draw all possible sequences for the original tripeptide.arrow_forward
- Humans are able to digest amylose, but not cellulose. What structural features of these polysaccharides might be responsible for this? O amylose contains only beta glycosidic bonds where cellulose contains alpha glycosidic bonds O amylose contains only beta glycosidic bonds where cellulose contains alpha glycosidic bonds amylose contains only alpha peptide bonds where cellulose contains beta peptide bonds amylose contains only alpha glycosidic bonds where cellulose contains beta glycosidic bondsarrow_forwardWhich of the following is FALSE? a. D-altrose and D-talose have the same osazones. b. D-glucose and D-galactose have different osazones. c. Trioses and tetroses cannot form the furfural derivatives because of their inability to form the 5-membered ring. d. Barfoed’s reagent, a weaker oxidizing agent than Benedict’s reagent, can only oxidize monosaccharides.arrow_forwardDraw a structural formula for the product formed when alanine is treated with the following reagents. (a) Product from (c), L-Alanine ethyl ester, DCC (b) Product from (d), L-Alanine ethyl ester, DCCarrow_forward
