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.]

Especially in the field of vitamins, amino acids, pharmaceutical raw materials and cosmetic raw materials, we have more than 20 years of production and sales experience. All products meet the requirements of high international export standards and have been recognized by customers all over the world. Our manufacture basement & R&D center located in National Aerospace Economic & Technical Development Zone Xi`an Shaanxi China. Now not only relying on self-cultivation and development as well as maintains good cooperative relations with many famous research institutes and universities in China. Now, we have closely cooperation with Shanghai Institute of Organic Chemistry of Chinese Academy of Science, Beijing Institute of Material Medical of Chinese Academy of Medical Science, China Pharmaceutical University, Zhejiang University. Closely cooperation with them not only integrating Science and technology resources, but also increasing the R&D speed and improving our R&D power. Offering Powerful Tech supporting Platform for group development. Keep serve the manufacture and the market as the R&D central task, focus on the technical research.  Now there are 3 technology R & D platforms including biological extract, microorganism fermentation and chemical synthesis, and can independently research and develop kinds of difficult APIs and pharmaceutical intermediates. With the strong support of China State Institute of Pharmaceutical Industry (hereinafter short for CSIPI), earlier known as Shanghai Institute of Pharmaceutical Industry (SIPI), we have unique advantages in the R & D and industrialization of high-grade, precision and advanced products.  Now our Group technical force is abundant, existing staff more that 1000 people, senior professional and technical staff accounted for more than 50% of the total number of employees, including 15 PhD research and development personnel, 5 master′ S degree in technical and management personnel 9 people. We have advanced equipment like fermentation equipment and technology also extraction, isolation, purification, synthesis with rich production experience and strict quality control system, According to the GMP required, quickly transforming the R&D results to industrial production in time, it is our advantages and our products are exported to North and South America, Europe, Middle East, Africa, and other five continents and scale the forefront in the nation, won good international reputation.  We believe only good quality can bring good cooperation, quality is our key spirit during our production, we are warmly welcome clients and partner from all over the world contact us for everlasting cooperation, Leader will be your strong, sincere and reliable partner in China.
