Answer #1

An aldohexose is a hexose with an aldehyde group on one end.

The aldohexoses have four chiral centres for a total of 16 possible aldohexose stereoisomers (24). Of these, only three commonly occur in nature: D-glucose, D-galactose, and D-mannose. The D/Lconfiguration is based on the orientation of the hydroxyl at position 5, and does not refer to the direction of optical activity.

There are eight D-aldohexoses as shown, and eight L-aldohexoses which are their enantiomers or mirror images.

  • D-Allose

  • D-Altrose

  • D-Glucose

  • D-Mannose

  • D-Gulose

  • D-Idose

  • D-Galactose

  • D-Talose
