Question

question
what type of functional group is formed by the glycosidic link between two monosaccharides?
select the correct answer below:
ethyl group
alkyl group
ether group
hydroxyl group

Explanation:

A glycosidic link is formed when two monosaccharides react. In this reaction, an -OH group (from one monosaccharide) reacts with the hemi - acetal or hemi - ketal group (of another monosaccharide). The reaction results in the formation of a C - O - C bond. The C - O - C functional group is an ether group.

• An ethyl group (\(-C_2H_5\)) is an alkyl substituent and not a functional group formed in glycosidic linkages.
• An alkyl group (\(-R\), where \(R\) is a hydrocarbon chain) is also not a functional group formed in glycosidic linkages.
• A hydroxyl group (\(-OH\)) is a reactant in the formation of glycosidic linkages, not the product of the linkage formation.

So, the functional group formed by the glycosidic link between two monosaccharides is an ether group.

Answer:

C. ether group
