代谢终产物

通过HPLC-MS分析发现DMF降解的主要中间产物为甲酰胺，氯的主要代谢终产物为NH4+。

By the result of HPLC-MS analysis , we find that the intermediate material of DMF degradation is formamide and metabolic end product is NH4 + .

并对两组患者治疗前后的血清NO及血浆ET、NPY、ANP、CGRP及临床症状评分的变化情况进行对照比较（NO以其代谢终产物NO3-和NO2-代替）。

The level changes of serum NO , plasma ET , NPY , ANP and CGRP and clinical symptom score were compared before and after treatment in the two groups .

应用活化镉还原剂与Griess反应结合法及放射免疫分析法分别测定用药前后血清NO代谢终产物硝酸基（NO3-）及血浆ET水平，并观察血压变化。

Serum nitrate ( NO 3 - ), the end products of NO and plasma ET were measured by activated cadmium reducer combined with Griess reaction and radioimmunoassay respectively before and after infusion of hANP or placebo . Blood pressure changes were observed .

酒精发酵中代谢终产物抑制消除方法进展

Proceeding of the Study on Depressing the Metabolin Inhibition During Alcohol Fermentation

尿酸是人体嘌呤碱基分解代谢终产物，经肾脏排泄。

Uric acid as the end-product of purine metabolism in human body is excreted through kidney .

动物体内，嘌呤代谢的终产物因物种不同而存在很大差异。

In animals , the end products of purine degradation vary greatly from species to species .

甲烷是瘤胃微生物代谢的终产物之一，对动物而言它是能量的损失，对环境而言是温室气体之一，然而对能源而言它又是可燃性气体，因此瘤胃产甲烷菌的研究越来越受到重视。

Methane is one of the end-products in the rumen , which is energy loss for host animals , green house gas for the environment , and also important energy resource in the ages of energy crisis .

在许多物种体内均发现有尿酸氧化酶，但在鸟类及一些高等灵长类动物（如猿和人类）的体内却缺乏具有功能的尿酸酶，而是以尿酸作为嘌呤代谢的终产物排出体外。

Urate oxidase has been found in the body of many species , while birds and some higher primates ( eg apes and humans ) lack functional urate oxidase in vivo and excrete uric acid as the end product of purine metabolism .

人类由于基因突变而缺乏活性尿酸酶，这导致人类以尿酸作为嘌呤代谢的终产物。当人血液中尿酸浓度高于其溶解度（高尿酸血症）时可引起尿酸性肾病和痛风性关节炎。

Human beings lack active uricase because of gene mutations , leading to uric acid as the end product of purine metabolism and resulting in the development of urate nephropathy and gouty arthritis when the concentration of uric acid reaches its solubility limit in blood ( hyperuricemia ) .

BaP是间接致癌物，需在体内代谢生成活性代谢终产物才具有强烈的致癌作用。

BaP is an indirect carcinogen , which has not strong carcinogenesis until it need to be metabolized into activate ultimate matters in vivo .

本研究借鉴动物体内的Tyr代谢模式，外源添加芳香族氨基酸及其代谢中间产物和终产物来处理植物，进一步寻找基因作用的节点。

Learning from Tyr metabolism in vivo model , we treat plants with exogenous aromatic amino acids and their metabolic intermediates and end products to further study gene working site .
