Property: white crystal powder, odorless; specific gravity: 1.585; melting point: 154 -158 ; specific optical rotation: [α]20D (C=5, H2O, 24h) 100° +104° Boiling point : 160 . It is soluble in water, slightly soluble in ethanol, insoluble in ether, methanol and acetone. One portion of L- arabinose can be dissolved in 48 portions of 90% ethanol at 12 .
l-arabinose is an aldopentose, a sweet material with no energy naturally synthesized. It can inhibit blood glucose elevation induced by sucrose intake, so it can inhibit obesity, prevent hyperglycemia .L-arabinose can be adopted as a pharmaceutical intermediate, or used for preparation of bacterial medium and synthesis of essence in biological industry.
