科学家在对同一种物质停止研讨的时分，会发现其有很多不同，而通常会依据其不同的性质停止命名和划分。我们在理解一些化学物质的时分，通常会听到一水或者无水的前缀，其实并不是它们能否含有水，而是分子构造的不同。在对葡萄糖的研讨过程中，人们发现了一水葡萄糖和无水葡萄糖这两种物质，并且对其停止了不同水平的应用。
When scientists stop discussing the same substance, they will find that it has many differences, and usually stop naming and classifying according to its different properties. When we understand some chemicals, we usually hear the prefix of water or anhydrous. It is not whether they contain water or not, but the difference of molecular structure. During the study of glucose, two substances, monohydrate glucose and anhydrous glucose, have been found and applied at different levels.
一水葡萄糖和无水葡萄糖的分子构造一水葡萄糖分子构造和异构体。
Molecular structure of monohydrate and anhydrous glucose Molecular structure and isomer of monohydrate glucose.
药典注射葡萄糖质量指标共17项，其中一水葡萄糖与无水葡萄糖指标完整相同的11项：分子量、比旋度、乙醇溶液廓清度、枯燥失重、重金属5项有差异；微生物限度无水葡萄糖未标明。但要阐明的是无水葡萄糖规范由网上查得，能否有误难以肯定。
There are 17 quality indexes of injected glucose in Chinese Pharmacopoeia, among which 11 indexes of monohydrate and anhydrous glucose are identical: molecular weight, specific rotation, clearance of ethanol solution, dry weight loss, heavy metal 5 items are different; microbial limit anhydrous glucose is not marked. But to clarify that the specification of anhydrous glucose is found online, it is difficult to determine whether there are errors.
质量规范上，普通无水葡萄糖应略优于一水葡萄糖，药典从指标上能够看出，英、美药典，固然指标分歧，但因称取样品量相同，同样与规范比拟，实践上要严一些
In terms of quality standards, general anhydrous glucose should be slightly better than monohydrate glucose. The Chinese Pharmacopoeia can see from the indicators that although the indicators are different between British and American Pharmacopoeia, they are also stricter in practice because of the same sample size.
内在质量上因工艺不同，普通无水葡萄糖略高于一水葡萄糖，如结晶过程，无水葡萄糖结晶原液纯度要高才干结晶，而一水葡萄糖结晶原液纯度稍低也能结晶；一水糖结晶采取降温结晶，易受微生物污染，无水糖结晶采取煮糖结晶，不容易受微生物污染。
In terms of internal quality, due to different processes, general anhydrous glucose is slightly higher than monohydrate glucose. For example, in crystallization process, the purity of anhydrous glucose crystallization stock liquid should be high before crystallization, while the purity of monohydrate crystal stock liquid is slightly low, it can also crystallize. Crystallization of monohydrate takes cooling crystallization, which is easy to be polluted by microorganisms, while crystallization of anhydrous sugar takes boiling sugar crystallization, which is not easy to be polluted by microorganisms.
价钱上因水分差别，普通无水葡萄糖价钱高于一水葡萄糖10元以上。总的看，一水葡萄糖和无水葡萄糖只需质量符合请求，都可同样运用、消费和运用部门要思索，肯定取舍。
The price of ordinary anhydrous glucose is higher than 10 yuan of monohydrate glucose because of the difference of water content. Generally speaking, monohydrate and anhydrous glucose can be used equally as long as their quality meets the requirements, and the departments of consumption and utilization need to think comprehensively and make sure their choices.
