On the basis of the kinetic equation of substrate reaction in the presence of urea or guanidine hydrochloride, all microscopic kinetic constants for the free enzyme and enzyme-substrate binary and ternary complexes have been determined. The results of the present studies indicate that:①In the presence of urea or guanidine hydrochloride, enzyme-substrate complexes lose their activity less rapidly than the free enzyme. Therefore, both substrates, NADPH and 7, 8-dihydrofolate, protect dihydrofolate reductase against inactivation.②The denaturation of dihydrofolate reductase by urea follows single-phase kinetics, and changes in enzyme activity and tertiary structure proceed simultaneously in the unfolding process, so it may be an"all or none"process.③The GdnHCl-induced unfolding of the dihydrofolate shows a biphasic transition, while the change in the enzyme activity is a single exponential process. The rate constant of inactivation is consistent with that of the fast conformational change. Therefore, the kinetic intermediate of protein unfolding should be a partially folded and inactive form.
我们根据在脲或盐酸胍存在下的底物反应动力学方程求得游离酶和酶底物二元、三元复合物的微观动力学常数，结果表明：①酶-底物二元、三元复合物的失活速度明显慢于游离酶，说明两个底物二氢叶酸和NADPH对酶的失活都具有一定程度的保护作用；②在脲作用下，酶的失活和构象变化均为单指数项过程，而且酶的活力丧失和三级结构变化是同时发生的，说明二氢叶酸还原酶的脲变性可能是一个"全或无"的两态过程；③在盐酸胍作用下，酶的构象变化为两相过程，而失活则是单指数项过程，酶分子构象变化的快相速度常数与失活速度常数基本一致，因此我们认为二氢叶酸还原酶的盐酸胍变性过程中存在一个没有活力、但仍具备一定空间结构的变性中间体。

The differences of providing amino acid to kernel of different winter wheatculfivars.93-52 with high protein content in kernel had highest content of amino acid innutrition organs,indicated 93-52 can provide abundance material for protein synthesis ofkernel,namely the source in full,so the content of amino acid in kernel was highest;Compared Lumai21 with Jinanl7,the amino acid content in leaf of Lumai21 was a littlehigher than Jinan17,but the amino acid content in stem、sheath and spike was obviouslylower than Jinan17,also the amount of amino acid restored in nutrition organs was large,the translocation degree was low to kernel,namely the flow was not fluency,which wasthe main reason of low content of amino acid in kernel.
小麦不同品种向籽粒供应氨基酸水平的差异。籽粒蛋白质含量高的93-52各营养器官中的游离氨基酸含量均最高，说明93-52籽粒蛋白质合成所需底物供应充足，即源足，因而其籽粒游离氨基酸含量最高。鲁麦21和济南17相比，鲁麦21叶片中的游离氨基酸含量虽略高于济南17，但茎鞘和穗中的游离氨基酸含量却明显比济南17低，并且在后期鲁麦21营养器官中游离氨基酸滞留的多，向籽粒中的转移程度低，即流不畅，是造成鲁麦21籽粒游离氨基酸含量低的主要原因之一。

The comparisons of biochemistry between OP and OR rats The differences between OP and OR rats included not only body weight, but lipids metabolism and insulin sensitivity as well, characterized with insulin resistance, increasing in serum free fatty acids and ketone body, and hepatic TC and TG in OP rats. However, no significant differences were observed in serum TG, TC, LDL, HDL and fasting glucose between OP and OR rats.⑶Comparisons of metabolites in serum, urine and liver tissue between OP and OR rats①There were significant differences in amino acids concentration between OP and OR rats,especially in liver tissue, such as high concentrations in ketogenic and glucogenic amino acids in OP rats, suggesting differences in amino acids metabolism;② The different metabolites between OP and OR rats included increasing of various saturated fatty acids and decreasing of polyunsaturated fatty acids in OP rats;③The urinary metabolites analysis indicated that different structure or metabolism of gut microflora might exist between the two phenotypes, which probably influenced the regulation of body weight gain;④The end-products of catecholamines in urine and intermediates of krebs cycle in serum in OP rats were all up-regulated, suggesting that the activity of sympatheic nervous system and energy metabolism was higher in OP rats than OR rats.

According to the result, we believed that the reason resulted in the low sensitivity was that the marker residue compound MQCA structure has changed after conjugated with protein and the antibody induced by the conjugation could not recognize the free MQCA in the ci-ELISA. Therefore we designed some hapten which could reserve the marker residue structural speciality mostly. After synthesis route selection and optimum, the hapten 7-Hydroxymethyl-3-methyl-quinoxaline-2-carboxylic acid was synthesized, used 4-methyl-2-nitroaniline as the start material via six steps, such as oxidation cyclization, bromize reaction, hydrolysis, Beirut reaction, reduction, hydrolysis. This work established basis for producing the high affinity antibody and developing the sensitive ELISA residue detection method.
