任何物質(zhì)的性質(zhì)特點(diǎn)都是十分重要的東西，它能影響著一個(gè)物質(zhì)的操作、儲運(yùn)、制作、應(yīng)用等多個(gè)方面，需要我們多多了解，才能熟練掌握它的使用方法。無水葡萄糖是自然界分布特別廣泛的單糖，它含五個(gè)羥基，一個(gè)醛基，具有多元醇和醛的性質(zhì)。其主要的化學(xué)性質(zhì)介紹如下。
The properties and characteristics of any material are very important things, which can affect the operation, storage and transportation, production, application and other aspects of a material. We need to know more about it to master its use methods. Anhydrous glucose is a kind of monosaccharide widely distributed in nature. It contains five hydroxyl groups and one aldehyde group. It has the properties of polyol and aldehyde. The main chemical properties are as follows.
1、分子中的醛基，有還原性，能與銀氨溶液反應(yīng)：CH2OH（CHOH）4CHO+2Ag（NH3）2OH（水浴加熱）→CH2OH（CHOH）4COONH4+2Ag↓+3NH3+H2O，被氧化成葡萄糖酸銨。
1. The aldehyde group in the molecule is reductive and can react with silver ammonia solution: CH2OH (Choh) 4cho + 2ag (NH3) 2OH (water bath heating) → CH2OH (Choh) 4coonh4 + 2ag ↓ + 3nh3 + H2O, which is oxidized to ammonium gluconate.
2、醛基還能被還原為己六醇。
2. The aldehyde group can also be reduced to hexanol.
3、分子中有多個(gè)羥基，能與酸發(fā)生酯化反應(yīng)。
3. There are many hydroxyl groups in the molecule, which can react with acid.
4、葡萄糖在生物體內(nèi)發(fā)生氧化反應(yīng)，放出熱量（C6H12O6+6O2（氧氣）+6H2O==6CO2+12H2O+能量）。
4. Glucose is oxidized in organism and gives out heat (C6H12O6 + 6o2 (oxygen) + 6H2O = = 6CO2 + 12H2O + energy).
5、無水葡萄糖能用淀粉在酶或硫酸的催化作用下水解反應(yīng)制得。
5. Anhydrous glucose can be prepared by hydrolysis of starch catalyzed by enzyme or sulfuric acid.
6、植物光合作用：6CO2+6H2O（葉綠素、陽光催化）——C6H12O6+6O2。
6. Plant photosynthesis: 6CO2 + 6H2O (chlorophyll, sunlight Catalysis) - C6H12O6 + 6o2.
7、葡萄糖與新制氫氧化銅反應(yīng)方程式：CH2OH（CHOH）4CHO+2Cu（OH）2-加熱->CH2OH（CHOH）4COOH+Cu2O↓+2H2O。
7. The reaction equation of glucose with new copper hydroxide is CH2OH (Choh) 4cho + 2Cu (OH) 2 - heating > CH2OH (Choh) 4cooh + Cu2O ↓ + 2H2O.
8、葡萄糖在一定條件下分解成為水和二氧化碳。
8. Glucose is decomposed into water and carbon dioxide under certain conditions.
9、麥芽糖的水解：C12H22O11+H2O（催化劑）→2CH2OH（CHOH）4CHO。
9. Hydrolysis of maltose: C12H22O11 + H2O (catalyst) → 2ch2oh (Choh) 4cho.
10、淀粉和纖維素水解：（C6H10O5）n+nH2O（催化劑）→nCH2OH（CHOH）4CHO。
10. Hydrolysis of starch and cellulose: (C6H10O5) n + nH2O (catalyst) → nch2o (Choh) 4cho.
無水葡萄糖在我們的日常生活中應(yīng)用特別廣泛，都與它的上述化學(xué)性質(zhì)離不開。它是活細(xì)胞的能量來源和新陳代謝中間產(chǎn)物，即生物的主要供能物質(zhì)。植物可通過光合作用產(chǎn)生葡萄糖。它在糖果制造業(yè)和醫(yī)藥領(lǐng)域有著廣泛應(yīng)用。
Anhydrous glucose is widely used in our daily life because of its above chemical properties. It is the energy source of living cells and the intermediate product of metabolism, that is, the main energy supply material of organisms. Plants produce glucose through photosynthesis. It is widely used in candy manufacturing and medicine.
