Step by step solution

Glycosides

鈥楪lycosides鈥� are the acetals in organic chemistry having an alkoxy (OR) group attached to the anomeric carbon (C1). These are assigned by $伪$ and $尾$ labelsand are generated when a monosaccharide is treated with alcohol and HCl.

Reaction of β-D-mannose and α-D-glucose with CH3CH2OH and HCl.

a. When $尾 - D - mannose$ is treated with ${CH}_{3} {CH}_{2} OH$ (ethanol) and HCl, it results in the formation of two glycosides shown below:

$尾 - D - mannose$ on treatment with ethanol and HCl

b. When $伪 - D - glucose$ is treated with (ethanol) and HCl, it results in the formation of two glycosides shown below:

$伪 - D - glucose$ on treatment with ethanol and HCl

When β-D-fructose is treated with CH3CH2OH and HCl.

c. When $尾 - D - fructose$ is treated with ${CH}_{3} {CH}_{2} OH$ (ethanol) and HCl, it results in the formation of two glycosides shown below:

$尾 - D - fructose$ on treatment with ethanol and HCl
