对于活细胞的能量来源和新陈 代谢的中间产物葡萄糖，以及有着丰富营养价值和药用价值的水果葡萄，我们都是不陌生的。在日常食用中，我们肯定无数次产生过疑问，这两种物质之间有什么关系呢？下面就一起来详细了解一下。
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，葡萄糖并不单纯的等价为葡萄中的糖分（其实葡萄糖的甜度比果糖、蔗糖都差远了），而是自然界分布重要的一种单糖，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，会以游离或是结合的形式存在。在生物（动植物）内部，葡萄糖多以游离形式存在，其中在葡萄、无花果等甜果及蜂蜜中，游离的葡萄糖含量较多。结合形式的葡萄糖主要存在于糖原、淀粉（像土豆、大麦中都含有的）、纤维素（蔬菜中常含有）、半纤维素等多糖中。此外，一些寡糖如：麦芽糖、蔗糖、乳糖以及各种形式的糖苷中也含有葡萄糖。葡萄糖是生物体内新陈 代谢不可缺少的营养物质。
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.
植物通过众所周知的光合作用，就会生成葡萄糖：6CO2+6H2O=（叶绿素）=>C6H12O6+6O2。于葡萄糖和葡萄的关系，那是因为一开始葡萄糖确实是从葡萄中提取出来的。
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.
综上所述，除了葡萄糖一开始的发现之外，它与葡萄之间似乎并没有太多的交集，只是两种物质都是甜味的而已。然后类似“葡萄糖”的命名方法，在化学和生物学中其实是有很多的，比如柠檬酸，草酸，蚁酸，苹果酸等，希望你们能有所认识。
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.
