Slider shows glucose in different representations. Position 1: Open-chain (Fischer projection) - shows the aldehyde group at top, 4 chiral centers. Position 2: Cyclization - the aldehyde reacts with the OH on C5, forming a ring. Show the mechanism: nucleophilic addition of OH to C=O, creating a hemi
