Derivative Type: Dihydrate
Properties: Monoclinic crystals from water or dil alcohol. mp 84-85°. Shows mutarotation. [a]D20 +111.7° ? +129.5° (c = 4). One gram dissolves in 0.4 ml water, 8.5 ml methanol, 220 ml abs alcohol. Dilute acids hydrolyze melibiose to D-glucose and D-galactose. Also split by emulsin and by bottom yeast. Reduces Fehling's soln. 3.5 g melibiose dihydrate are about as sweet as 1.0 g sucrose.
Melting point: mp 84-85°
