藥用級無水葡萄糖和一水葡萄糖有什么樣的區(qū)別？

結(jié)晶葡萄糖依制造工藝的不同可分為一水葡萄糖（C6H12O6.H2O）和無水葡萄糖。水結(jié)晶葡萄糖分為食品級葡萄糖和醫(yī)藥葡萄糖，食品級葡萄糖主要用于食品加工業(yè)及蔬菜保鮮行業(yè)。一水葡萄糖經(jīng)過加氫可制造山梨醇，醫(yī)藥級一水葡萄糖主要做為口服醫(yī)藥的原（輔）料。一水結(jié)晶葡萄糖再繼續(xù)加工能夠制造無水葡萄糖，無水葡萄糖主要用于制造醫(yī)藥針劑和輸液。 是復原糖，葡萄糖的化學簡式是CH2-OH(CH-OH)CHO，由于有-CHO（醛基），醛基能被氧化為-COOH（羧基），所以葡萄糖有復原性。
Crystalline glucose can be divided into monohydrate glucose (C6H12O6.H2O) and anhydrous glucose according to different manufacturing processes. Crystalline glucose is divided into food-grade glucose and pharmaceutical-grade glucose. Food-grade glucose is mainly used in food processing industry and vegetable preservation industry. Glucose monohydrate can be hydrogenated to produce sorbitol. Medical grade glucose monohydrate is mainly used as raw (auxiliary) material for oral medicine. Crystalline monohydrate glucose can be further processed to produce anhydrous glucose, which is mainly used in the manufacture of medical injections and infusion. The chemical formula of glucose is CH2-OH (CH-OH) CHO. Because there is - CHO (aldehyde group), aldehyde group can be oxidized to - COOH (carboxyl group), so glucose has resilience.
低聚糖具有與單糖相似的性質(zhì)：結(jié)晶性，有甜味，易溶于水，難溶或不溶于有機溶劑。其中局部有復原性如麥芽糖、乳糖、甘露三糖等，局部無復原性、如蔗糖、龍膽三糖等。 由許多單糖分子或其衍生物縮合而成的高聚物稱為多糖，又稱為高聚糖。可分為同多糖和雜多糖兩類。由一種單糖縮合構(gòu)成的多糖稱為同多糖，兩種或兩種以上不同單糖分子組成的多糖稱為雜多糖。單體為葡萄糖的同多糖時能夠用無水葡萄糖來權(quán)衡，否則不能用無水葡萄糖來丈量。
Oligosaccharides have similar properties to monosaccharides: crystallinity, sweetness, solubility in water, insolubility or insolubility in organic solvents. Among them, there are local resilience, such as maltose, lactose, mannose and so on, while there is no local resilience, such as sucrose, gentian trisaccharide and so on. Polymers formed by condensation of many monosaccharide molecules or their derivatives are called polysaccharides, or polysaccharides. It can be divided into homologous polysaccharides and heteropolysaccharides. Polysaccharides consisting of one kind of monosaccharide condensation are called homopolysaccharides, and polysaccharides consisting of two or more different monosaccharide molecules are called heteropolysaccharides. When the monomer is glucose, the polysaccharide can be weighed by anhydrous glucose, otherwise it can not be measured by anhydrous glucose.
