| | Melibiose Usage And Synthesis |
| Chemical Properties | White powder | | Uses | Melibiose has been used in a study to improve the preparation of benzoylated ethyl 1-thioglycosides. It has also been used in a study to investigate the effect of water plasticization on the molecular mobility and crystallization tendency of amorphous disaccharides. | | 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. | | General Description | Melibiose is a carbon substrate. | | 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.] |
