Cyclic hemiacetal form of glucose - hiro-seiko.com
WebbThis complex chemistry is the result of reversible reactions between carbonyl and hydroxyl groups within a sugar molecule, in which aldohexoses, such as glucose, form cyclic hemiacetals and ketohexoses, such as fructose, form cyclic hemiketals. WebbFive- and six-membered rings are readily formed and are very stable; their sizes also allow the development of aromatic character. Seven-membered rings and larger are stable but less readily formed and relatively less well investigated. Three-membered rings help desk association
