L-Arabinose Chemical Properties,Uses,Production
Chemical Properties
White to off white crystalline powder
Uses
A base component of hemicellulose and pectin, critical biopolymers.
Purification Methods
beta-L-(+)-Arabinose is recrystallised slowly, twice, from 80% aqueous EtOH, then dried under vacuum over P2O5. It can also be purified by heating the arabinose (200g) with glacial acetic acid (300mL) on a boiling water bath for 45minutes, cooling, filtering, washing with 95% EtOH (500mL) in four portions and drying at 56-60o over P2O5. It has been recrystallised from 5times its weight of 76% EtOH using charcoal (10g) to yield 127g, m 155-157o, [] 20D +190.6o and mutarotating to +104o (c 4, H2O).

Mode of action
L-arabinose has been shown to slow down glucose absorption by inhibiting the intestinal enzyme sucrase in an uncompetitive manner. Sucrase is present in the brush border of the intestine and critical for hydrolysing sucrose into a glucose and fructose molecule[1].
