l-arabinose is a kind of aldopentoses, it's a low-calurie sweetener, it inhibits the sucrase activity and prevents increasing of blood glucose, therefore, it can prevent fat accumulation and against high blood glucose disease.
L-arabinose is more common than D-arabinose in nature, it can be used as pharmaceutical intermediate, preparing culture medium and be used for synthesis in the flavour industry.
