葡萄糖和葡萄之間的關系？

對于活細胞的能量來源和新陳 代謝的中間產物葡萄糖，以及有著豐富營養價值和藥用價值的水果葡萄，我們都是不陌生的。在日常食用中，我們肯定無數次產生過疑問，這兩種物質之間有什么關系呢？下面就一起來詳細了解一下。
We are familiar with the energy source of living cells, the intermediate product of metabolism, glucose, and the fruit grape with rich nutritional value and medicinal value. In daily consumption, we have doubted countless times, what is the relationship between these two substances? Let's learn more about it.
前提你要明白，葡萄糖并不單純的等價為葡萄中的糖分（其實葡萄糖的甜度比果糖、蔗糖都差遠了），而是自然界分布重要的一種單糖，分子式是C6H12O6。
If you understand, glucose is not simply equivalent to the sugar in grapes (in fact, the sweetness of glucose is far worse than fructose and sucrose), but an important monosaccharide distributed in nature, with the molecular formula of C6H12O6.
天 然的葡萄糖，會以游離或是結合的形式存在。在生物（動植物）內部，葡萄糖多以游離形式存在，其中在葡萄、無花果等甜果及蜂蜜中，游離的葡萄糖含量較多。結合形式的葡萄糖主要存在于糖原、淀粉（像土豆、大麥中都含有的）、纖維素（蔬菜中常含有）、半纖維素等多糖中。此外，一些寡糖如：麥芽糖、蔗糖、乳糖以及各種形式的糖苷中也含有葡萄糖。葡萄糖是生物體內新陳 代謝不可缺少的營養物質。
Natural glucose exists in the form of free or combined glucose. In the interior of organisms (animals and plants), glucose mostly exists in the form of free glucose, and the content of free glucose is more in grapes, figs and honey. The combined form of glucose mainly exists in glycogen, starch (such as potatoes and barley), cellulose (often found in vegetables), hemicellulose and other polysaccharides. In addition, some oligosaccharides such as maltose, sucrose, lactose and various forms of glycosides also contain glucose. Glucose is an indispensable nutrient in metabolism.
植物通過眾所周知的光合作用，就會生成葡萄糖：6CO2+6H2O=（葉綠素）=>C6H12O6+6O2。于葡萄糖和葡萄的關系，那是因為一開始葡萄糖確實是從葡萄中提取出來的。
Through the well-known photosynthesis, plants produce glucose: 6CO2 + 6H2O = (chlorophyll) = > C6H12O6 + 6o2. As for the relationship between glucose and grapes, that's because glucose was actually extracted from grapes in the beginning.
綜上所述，除了葡萄糖一開始的發現之外，它與葡萄之間似乎并沒有太多的交集，只是兩種物質都是甜味的而已。然后類似“葡萄糖”的命名方法，在化學和生物學中其實是有很多的，比如檸檬酸，草酸，蟻酸，蘋果酸等，希望你們能有所認識。
To sum up, in addition to the discovery of glucose at the beginning, it seems that there is not much intersection between glucose and grape, but both substances are sweet. Then, there are many ways to name glucose in chemistry and biology, such as citric acid, oxalic acid, formic acid, malic acid and so on. I hope you can get to know them.
