Ugt1a9 is mainly existed in liver , but some reports indicated that the expression of ugt1a9 were also found in some extrahepatic tissues such as colon , kidney , prostate , testis , breast , ovary , skins and some tumor tissues 但是ugts的组织分布并不局限于肝脏，许多肝外组织也表现出一定的葡醛酸转移酶的活性。 ugt1a9主要存在于肝中，但也有发现其他组织如结肠、肾脏、前列腺、睾丸、乳腺、卵巢、皮肤以及肿瘤组织中有所表达。
No report was found about the metabolism of isoflavone by ugt1a9 . the substrates metabolized by ugts encompass a wide range of structurally unrelated substances . previous studies revealed that the individual ugts isozymes tend to exhibit un - strict and overlapping patterns of substrate specificity 过去的研究认为，葡醛酸缀合反应有各种底物，而且不同的同工酶催化不同结构类型的化合物，但现在认识到ugts与底物的关系不是?一对应的关系，底物谱相互有重叠。
Propofol and paracetamol are compounds that have phenol hydroxyl and propranolol and propafenone are those that have aliphatic ones . among the four compounds , propofol is the specific substrate of ugt1a9 and can be served as the comparison reference of enzymatic activity . based on the study of four compound , four kinds of isoflavone compounds , i . e . , quercetin , kaempferol , isorhamnetin and 在上述四种化合物研究的基础上，考用类黄酮化合物对叭xs有各种影响，并且具有各种酚羟基结构，本实验选择了四种类黄酮化合物即们皮素、山费酚、异鼠辛素和芦丁作为底物，观察ix ； 1 ’ iag对它们代谢的作用情况，试图了解ijgtiag在这些化合物的葡醛酸代谢过程中所起的作用。
Udp - glucuronosyltransferases ( ugts ) are glycoproteins localized in the endoplasmic reticulum that catalyze the conjugation of a broad variety of endogenous and exogenous lipophilic aglycon substrates ( such as bilirubin , steroid hormone and drugs , insecticide , etc ) with glucuronic acid using udp - glucuronic acid ( udpga ) as the sugar donor . ugts are a gene superfamily of phase ii drug - metabolizing enzymes , they are responsible for the glucuronidation of a significant number of different functional groups ( e . g Ugts能催化各种各样外源和内源的亲脂性糖苷配基底物与葡醛酸的结合，该反应是机体清除外源性(如药物和杀虫剂)和内源性(如胆红素和甾体激素)亲脂性化合物的一个主要方式，也是药物相代谢的重要方式。
Endogenous elicitor activity , termed cdw , was prepared from the cell walls of suspension - cultured ginseng ( panax ginseng c . a . meyer ) cells via cellulase degradation . cdw activated in vitro the nadph oxidase activity of isolated plasma membranes and stimulated in vivo h2o2 generation by ginseng cell suspensions 在本研究工作中，金瓜炭疽细胞壁激发子与脱乙酰几丁质是来源于真菌细胞壁的真激发子，人参细胞壁降解物与寡聚半乳糖醛酸是来源于植物细胞壁的内源激发子。
[ objective ] heparin is linear polysaccharides consisting of repeating disaccharide unit backbones of n - acetyl - d - glucosamine that is linked to d - glucuronic acid . the disaccharide repeat unit can be modified to include n - and o - sulfation ( 6 - o and 3 - o sulfation of the glucosamine and 2 - o sulfation of the uronic acid ) . these specific sulfate patterns are involved in the interaction of heparin with other molecules [目的]肝素是由n -乙酰葡萄糖胺与d -葡萄糖醛酸以1 4糖苷键连接起来的重复二糖单位组成的线性多糖，葡萄糖胺可带有n -硫酸基团，可在c6上形成0 -硫酸酯，带有硫酸基团的独特结构参与了肝素与其他分子的相互作用。
