糖合成

We're not talking about complex carbohydrates, which are merely long strings of sugars.

我们不讨论碳水化合物，那是一长串糖的合成物。

黄瓜经喷施人工合成的植物抗病性诱导剂葡聚六糖诱导后，黄瓜霜霉病的发病程度显著降低。

This is transformed into anomeric acetates 16, which is used for the synthesis of a number of 2＇, 3＇-dideoxy-2＇-trifluoromethylnuclosides via Vorbruggen glycosylation reaction. At the same time, L-2-tifluoromethyl-4-thiofuranosides 39 were also prepared from the key intermediate lactone.

从这一砌块出发，经由关键中间体2-三氟甲基-γ-丁内酯转化得到的化合物16的Vorbruggen糖苷化反应，合成了2＇，3＇-双脱氧-2＇-三氟甲基嘧啶核苷。

Heterotrophs , such as animals, use light from the sun indirectly by consuming the products of autotrophs, either directly or by consuming other heterotrophs.

的存在，几乎所有地球上的生命是因为光从太阳。大多数自养，如植物，利用阳光的能量把空气成简单的糖，一个过程称为光合作用。这些糖类随后作为基石和其他合成途径，使机体增长。

Roots grew preferentially, R/S ratio and phosphorous utilized efficiency are high; As the treated time prolongs, rubber mini-seedling buddings under the treatment of phosphorus deficiency is seriously restrained.

抽生期、古铜期和成熟期根系可溶性糖大量合成蛋白质，IAA含量高、iPA含量低，根系活力强，说明根系生长快、代谢旺盛、吸收能力强；淡绿期、稳定期则相反。

For long-term treatments, the rat administered daily by gavages for six weeks, the results of OGTT showed that guava fruit water or alcohol extracts could reduce the plasma glucose level in the diabetic Wistar rats, however there was on significant difference in insulin level among all tested groups. The results of carbohydrate metabolism showed diabetic Wistar rats administered with 200 or 400 mg/kg BW of guava fruit water or alcohol extracts could decrease more than 15% glucose-6-phosphatase and fructose-1,6-bisphosphatase activities, and it also increase more than 12% glucose-6-phosphate dehydrogenase activities to reduce inhibitory hexokinase from reducing glucose-6-phosphate level.

在醣类代谢方面，实验结果发现糖尿病鼠灌食番石榴果实水及乙醇萃取物六周后，肝脏醣质新生作用中丙酮酸合成肝醣之关键酵素glucose-6-phosphatase及fructose-1，6-bisphosphatase的酵素活性会降低15%以上；另一方面肝脏glucose-6-phosphate dehydrogenase酵素活性则明显增加12%以上，并造成glucose-6-phosphate浓度减少，进而降低其对hexokinase的抑制(因为hexokinase受其代谢产物G-6-P的浓抑制)，因此加速肝脏葡萄糖的糖解作用。

Plant polyprenols, which have similar structure and biological activity to dolichols in human body, are lipids of polymer with isoprenyl units. However, dolichols are key carriers in biosynthesis process of glycosyl derivatives with protein.

植物聚戊烯醇是一类异戊烯基结构聚合体的类脂化合物，与人体内多萜醇具有相似的结构特征和生理活性，而多萜醇是糖基与蛋白质生物合成的关键载体。

Vitami function as photoreceptor mechanism of retina, maintenance of integrity of epithelia, lysosome stability, glycoprotein synthesis.

它的作用有：视网膜光受体机制、维护上皮细胞的完整性、溶酶体的稳定性、糖蛋白的合成等。

Naturally occurring terpenes constitute the largest group of natural products with complicated and variable structures and a great number of important biological activities.2-Methyl-D-erythreitol 4-phosphate pathway is a newly found and established biosynthetic route for terpenoids and all the enzymes involved in this pathway can be used as targets for the screening of new antibiotics.

萜类化合物构成了最大的一个天然产物家族，结构复杂多变，且有许多重要的生理活性。2-甲基-D-赤藓糖醇4-磷酸途径是近年来发现并建立的一条萜类化合物的生物合成途径，其中所涉及到的酶均可作为靶标来进行新抗菌素的筛选。

By splicing in genes from other bugs, the company was able to engineer synthetic metabolic pathways—ones that do not exist in nature—that enable the bacteria to produce isoprene from the sugars found in plant materials such as sugar cane, corn cobs and switchgrass, a tall-growing variety native to North America.

Genencor的科学家们通过将大肠杆菌的基因与其它菌类基因接合，则能研发出前所未有的代谢合成途径，使细菌能从植物所含的糖类中制造出异戊二烯，这些含糖植物包括甘蔗、玉米棒和北美特有的变异品种柳枝稷等。
