Concept explainers
(a)
Interpretation:
If this monosaccharide is an aldose or a ketose and a hexose or a pentoses should be determined.
Concept introduction:
Carbohydrates and lipids are the energy sources. Carbohydrates are composed of carbon, hydrogen, and oxygen atoms. They are also known as saccharides because of their sweet taste.
They are classified into three categories, monosaccharide, oligosaccharide, and polysaccharides.
(b)
Interpretation:
The unusual about the monosaccharide should be explained.
Concept Introduction:
L-Fucose is a hexose deoxy sugar having molecular formula
(c)
Interpretation:
The monosaccharide formed should be identified if the L-fucose undergoes a reaction in which its terminal -CH3 group was converted to a CH2 OH group.
Concept introduction:
L-Fucose is a hexose deoxy sugar having molecular formula

- 2 Draw the structure of a disaccharide made up of two D-glucose units. The glycosidic bond is α-1,6-glycosidic bond.arrow_forwardConsider the tetrasaccharide stachyose drawn below. Stachyose is found in white jasmine,soybeans, and lentils. Because humans cannot digest it, its consumption causes flatulence. a. Is stachyose a reducing sugar?b. What product is formed when stachyose is treated with excess CH3I, Ag2O?c. What products are formed when the product in (e) is treated with H3O+?arrow_forwarda) Draw Haworth projections of both - and -anomers of D-fructose. Indicate which carbon is the anomeric carbon.b) Sucrose is a disaccharide made up of a molecule of D-fructose and D-glucose. Draw the structure of sucrose clearly indicating the linkage between the two monosaccharides and its biological significance.c) Tollen’s reagent is a very mild oxidizing agent which normally oxidize aldehydes but not ketones. However, both glucose and fructose give positive results with Tollen’s reagent and are classified as reducing sugars. Explain how fructose can also give positive results with Tollen’s reagent (illustrate using structures).arrow_forward
- Consider the tetrasaccharide stachyose drawn below. Stachyose is found in white jasmine, soybeans, and lentils. Because humans cannot digest it, its consumption causes flatulence.a. Label all glycoside bonds.b. Classify each glycosidic linkage as αα or ββ and use numbers to designate its location between two rings (e.g., 1→→4-ββ)-c. What products are formed when stachyose is hydrolyzed with H33O++?d. Is stachyose a reducing sugar?e. What product is formed when stachyose is treated with excess CH33I, Ag22O?f. What products are formed when the product in (e) is treated with H33O++?arrow_forwardCellobiose, a disaccharide obtained by the hydrolysis of cellulose, is composed of two glucose units joined together in a 1->4-ß-glycoside bond. What is the structure of cellobiose?arrow_forward- a)What is an isomer? b) What is a polymer, and a monomer? Please give examples. (2 points). 3.- Please define monosaccharide, disaccharide and polysaccharide. Please give examples.arrow_forward
- 35 Select from the menus to describe the following monosaccharide. Is this sugar D or L? Is this sugar an aldose or a ketose? How would the sugar be classified based on the number of carbons present?arrow_forwarda tetrose if it has 4 C's; What are these ?arrow_forwardThe C2-epimer of D-xylose is called (blank 1). The enediol rearrangementconverts an aldose into a (blank 2). The aldopentose embedded in RNA is(blank 3). An aldopentose would have (blank 4) possible stereoisomers,of whichBlankwould be D-sugars. An ketopentose would have (blank 4) possiblestereoisomers, of which (blank 5) would be D-sugarsarrow_forward
- 21. When xylose and glucose form a disaccharide will the linkage be alpha or beta? Use the 1 position of xylose and the 4 position of glucose to link the monosaccharides together. (see attached screenshot) a)beta b)alphaarrow_forwarda hexose if it has 6 C's, and so forth. ? Explainarrow_forwardSuppose you have two simple sugars, D-arabinose and L-tagatose. Both sugars cyclize and form a non-reducing disaccharide with the glycosidic bond oriented in the alpha position relative to each monosaccharide's structure. Give the full biochemical name for this disaccharide.arrow_forward
