Function:
1. L-arabinose can be used as a sucrose enzyme inhibitor to lower the Glycaemic Index(GI) of sucrose containing products
2. L-arabinose can be used in developing antiviral agents such as nucleoside analogues
3. L-arabinose can be used in various foods (except foods for infants or young children)
4. L-arabinose can be used as raw material for the synthesis of fine chemicals as well as pharmaceutical intermediate
5. L-arabinose can be used in preparing bacterial medium in biological industry
6. L-arabinose can be used in the synthesis of flavours.
