Rare sugar explained

A rare sugar is a sugar that occurs in limited quantities in nature.^[1] Rare sugars can be made using enzymes, choosing which enzymes to use if you know the substrate can be aided by the Izumoring-strategy.^[2]

Specific examples of rare sugars are:

• Allulose^[3]
• Allose
• Sorbose
• Tagatose
