一水葡萄糖好與無水葡萄糖哪個好你知道嗎？

科學(xué)家在對同一種物質(zhì)停止研討的時分，會發(fā)現(xiàn)其有很多不同，而通常會依據(jù)其不同的性質(zhì)停止命名和劃分。我們在理解一些化學(xué)物質(zhì)的時分，通常會聽到一水或者無水的前綴，其實并不是它們能否含有水，而是分子構(gòu)造的不同。在對葡萄糖的研討過程中，人們發(fā)現(xiàn)了一水葡萄糖和無水葡萄糖這兩種物質(zhì)，并且對其停止了不同水平的應(yīng)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.
一水葡萄糖和無水葡萄糖的分子構(gòu)造一水葡萄糖分子構(gòu)造和異構(gòu)體。
Molecular structure of monohydrate and anhydrous glucose Molecular structure and isomer of monohydrate glucose.
藥典注射葡萄糖質(zhì)量指標(biāo)共17項，其中一水葡萄糖與無水葡萄糖指標(biāo)完整相同的11項：分子量、比旋度、乙醇溶液廓清度、枯燥失重、重金屬5項有差異；微生物限度無水葡萄糖未標(biāo)明。但要闡明的是無水葡萄糖規(guī)范由網(wǎng)上查得，能否有誤難以肯定。
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.
質(zhì)量規(guī)范上，普通無水葡萄糖應(yīng)略優(yōu)于一水葡萄糖，藥典從指標(biāo)上能夠看出，英、美藥典，固然指標(biāo)分歧，但因稱取樣品量相同，同樣與規(guī)范比擬，實踐上要嚴(yán)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.
內(nèi)在質(zhì)量上因工藝不同，普通無水葡萄糖略高于一水葡萄糖，如結(jié)晶過程，無水葡萄糖結(jié)晶原液純度要高才干結(jié)晶，而一水葡萄糖結(jié)晶原液純度稍低也能結(jié)晶；一水糖結(jié)晶采取降溫結(jié)晶，易受微生物污染，無水糖結(jié)晶采取煮糖結(jié)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.
價錢上因水分差別，普通無水葡萄糖價錢高于一水葡萄糖10元以上?？偟目?，一水葡萄糖和無水葡萄糖只需質(zhì)量符合請求，都可同樣運用、消費和運用部門要思索，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.
