Which one of the following sets of monosaccharides forms sucrose?
- A \(\alpha\)-D-galactopyranose and \(\alpha\)-D-glucopyranose
- B \(\alpha\)-D-glucopyranose and \(\beta\)-D-fructofuranose
- C \(\beta\)-D-glucopyranose and \(\alpha\)-D-fructofuranose
- D \(\alpha\)-D-glucopyranose and \(\beta\)-D-fructopyranose
Answer & Solution
Correct Answer
(B) \(\alpha\)-D-glucopyranose and \(\beta\)-D-fructofuranose
Step-by-step Solution
Detailed explanation
Sucrose is a disaccharide composed of two monosaccharide units linked by a glycosidic bond. The two units are \(\alpha\)-D-glucopyranose and \(\beta\)-D-fructofuranose. The glycosidic linkage is formed between the C1 of \(\alpha\)-D-glucopyranose and the C2 of…
