1.	The hydroxyl group at which carbon is involved in ring formation in glucose?(a) C3(b) C4(c) C5(d) C6I had been asked this question in a job interview.I'd like to ask this question from Biomolecules Carbohydrates in chapter Biomolecules of Chemistry – Class 12
Answer» Right CHOICE is (C) C5 The EXPLANATION: Monosaccharides undergo intramolecular reaction to form cyclic hemiacetal structures. GENERALLY in aldoses, the C4 or C5 carbon is involved in cyclisation. In glucose, the hemiacetal (six-membered RING) is formed between the CHO group andthe OH group on the C5 carbon.
