  2. Pyranose - Wikipedia

    en.wikipedia.org/wiki/Pyranose

    The pyranose ring is formed by the reaction of the hydroxyl group on carbon 5 (C-5) of a sugar with the aldehyde at carbon 1. This forms an intramolecular hemiacetal . If reaction is between the C-4 hydroxyl and the aldehyde, a furanose is formed instead. [ 1 ]

  5. Furanose - Wikipedia

    en.wikipedia.org/wiki/Furanose

    The chemical structure of ribose in its furanose form. The wavy bond indicates a mixture of β-ribofuranose and α-ribofuranose. The furanose ring is a cyclic hemiacetal of an aldopentose or a cyclic hemiketal of a ketohexose.

  6. Hemiacetal - Wikipedia

    en.wikipedia.org/wiki/Hemiacetal

    In organic chemistry, a hemiacetal is a functional group the general formula R 1 R 2 C(OH)OR, where R 1, R 2 is a hydrogen atom or an organic substituent. They generally result from the nucleophilic addition of an alcohol (a compound with at least one hydroxy group ) to an aldehyde ( R−CH=O ) or a ketone ( R 2 C=O ) under acidic conditions.
