Interpretation Introduction
Interpretation:
The hexose that results by the hydrolysis of the glycoside bond of phrenosine is to be provided and analyzed; the structural formulas for cerebronic acid and sphingosine are to be drawn.
Concept introduction:
The simplest hydrolyzed form that is obtained from the carbohydrates is known as monosaccharide. Polysaccharides are those types of sugars which contain more than ten units of monosaccharides.
Hexose contains six carbon atoms and is a monosaccharide having a chemical formula

- Several compounds have been found to inhibit -lactamase, and drugs based on these compounds can be taken in combination with penicillins and cephalosporins to restore their effectiveness when resistance is known to be a problem. The commonly prescribed formulation called Augmentin is a combination of the -lactamase inhibitor shown below with amoxicillin (shown above). It is used to treat childhood ear infections when resistance is suspected, and many kids know it as the white liquid that tastes like bananas. Which of the statements below are true statements? 1. The stereochemistry of the fusion between the four-and five-membered rings in the inhibitor and amoxicillin are different. 2. The inhibitor possesses enol ether and allylic alcohol functional groups while the antibiotic possesses a phenol and a secondary amide functional group. 3. Neither the inhibitor nor the antibiotic contains strained rings. 4. Both 1 and 2 are true.arrow_forwardA D-aldopentose A is reduced to an optically active alditol. Upon Kiliani–Fischer synthesis, A is converted to two Daldohexoses, B and C. B is oxidized to an optically inactive aldaric acid. C is oxidized to an optically active aldaric acid. What are the structures of A–C?arrow_forwardAldohexoses A and B are formed from aldopentose C via a Kiliani–Fischer synthesis. Nitric acid oxidizes A to an optically active aldaric acid, B to an optically inactive aldaric acid, and C to an optically active aldaric acid. Wohl degradation of C forms D, which is oxidized by nitric acid to an optically active aldaric acid. Wohl degradation of D forms (+)-glyceraldehyde. Identify A, B, C, and D.arrow_forward
- A D-aldohexose A is formed from an aldopentose B by the Kiliani–Fischer synthesis. Reduction of A with NaBH4 forms an optically inactive alditol. Oxidation of B forms an optically active aldaric acid. What are the structures of A and B?arrow_forwardIn solution, glucose is mostly found in the cyclic hemiacetal state, which lacks an aldehyde group. How are mild oxidising agents able to oxidise glucose?arrow_forwardAn unknown carbohydrate of formula C12H22O11 reacts with Tollens reagent to form asilver mirror. An a@glycosidase has no effect on the carbohydrate, but a b@galactosidasehydrolyzes it to d-galactose and d-mannose. When the carbohydrate is methylated (usingmethyl iodide and silver oxide) and then hydrolyzed with dilute HCl, the products are2,3,4,6-tetra-O-methylgalactose and 2,3,4-tri-O-methylmannose.

- (a) Which of the d-aldopentoses will give optically active aldaric acids on oxidation with HNO3 ?(b) Which of the d-aldotetroses will give optically active aldaric acids on oxidation with HNO3 ?(c) Sugar X is known to be a d-aldohexose. On oxidation with HNO3, X gives an optically inactive aldaric acid. WhenX is degraded to an aldopentose, oxidation of the aldopentose gives an optically active aldaric acid. Determine thestructure of X.(d) Even though sugar X gives an optically inactive aldaric acid, the pentose formed by degradation gives an opticallyactive aldaric acid. Does this finding contradict the principle that optically inactive reagents cannot form opticallyactive products?(e) Show what product results if the aldopentose formed from degradation of X is further degraded to an aldotetrose.Does HNO3 oxidize this aldotetrose to an optically active aldaric acid?arrow_forwardDraw the structure of the expected product when monosaccharide A undergo mutarotation upon dissolving in water in the presence of Tollens reagent (AgNO3, NH4OH).arrow_forwardd-Glucuronic acid is found widely in plants and animals. One of its functions is to detoxify poisonous HO-containing compounds by reacting with them in the liver to form glucuronides. Glucuronides are water soluble and, therefore, readily excreted. After ingestion of a poison such as turpentine or phenol, the glucuronides of these compounds are found in urine. Draw the structure of the glucuronide formed by the reaction of beta-d-glucuronic acid and phenol.arrow_forward
