Chemical Properties

White powder

Definition

A disaccharide con- sisting of two glucose units in an alpha (1- 6)glycosidic linkage. It is an effector molecule that permits activation of the lac operon by binding to the repressor molecule.

Definition

A salt that has a single molecule of WATER OF CRYSTALLIZATION, such as sodium carbonate monohydrate, Na2CO3.H2O.

Definition

monohydrate: A crystalline compoundhaving one mole of water permole of compound.

Purification Methods

Melibiose crystallises as a hydrate from water or aqueous EtOH. The anomer is obtained by recrystallising 1g from a mixture of 0.35mL of H2O and 0.2mL of EtOH. It crystallises easily with m 179o and mutarotates from [] D 20 +166o to +142.3o (220minutes, c 4, H2O). Crystallisation from MeOH gives the anhydrous form which hydrates to the monohydrate in air. The anomer dihydrate m 85-86o mutarotates from [] D 20 +123.5o to +143.1o (c 4, H2O for anhydrous). [Fletcher & Diehl J Am Chem Soc 74 5774 1952, Beilstein 1 7 III/IV 3075, 17/7 V 206.]
