Step by step solution

01

Pyranose

Pyranose is a hexagonal ring having five carbons and one oxygen atom in a ring.The only difference between alpha (伪)and beta (尾) anomers is the OH group at C1 carbon. 伪means downward OH and尾 means upward OH.

02

3-D representation with a chair pyranose of a

The OH group at the C5 carbon is on the right side, which is D sugar. The group will come in an upward position. The 伪and尾anomers of part (a) are shown as,

Pyranose anomers of aldohexose a

03

3-D representation with a chair pyranose of b

It is a D-sugar because the OH at C5 is on the right side. So, group will come in the upward position. The 伪and尾anomers in part (b) is shown as,

Pyranose anomers of aldohexose b

What glycosides are formed when each monosaccharide is treated with CH3CH2OH, HCl:

(a) 尾-D-Mannose; (b)伪-D-glucose ; (c) 尾-D-fructose ?

A D-aldohexose A is formed from an aldopentose B by the Kiliani-Fischer synthesis. Reduction of A with forms an optically inactive alditol. Oxidation of B forms an optically active aldaric acid. What are the structures of A and B?

What two aldohexoses yield d-arabinose upon Wohl degradation?

Which d-aldopentoses are reduced to optically inactive alditols using NaBH4,CH3OH?

(a)Label all the O atoms that are part of a glycoside in rebaudioside A. Rebaudioside A, marketed under the trade name Truvia, is a sweet glycoside obtained from the stevia plant, which has been used for centuries in Paraguay to sweeten foods. (b)The alcohol or phenol formed from the hydrolysis of glycoside is called an aglycon. What aglycon and monosaccharides are formed by the hydrolysis of rebaudioside A?
