From 24th august of 2001 to 8th april of 2002, gala ( malus cv. gala ) and golden ( m. cv. golden delicious ), stored with three different models of cold storage, air condition and ultro - lower oxygen, were kindly provided in different sale time by inter - profession technique center of fruit and vegetable of france. the fruits were cut into three parts of the skin, pulp and core according to the human edible habit. the apple polyphenolics in the skin and pulp were determined by thiolysis hplc and unthiolysis hplc in institut national de la recherche agronomique, laboratoire de recherches cidricoles
為建立能全面測定蘋果果實多酚的hplc方法,同時為蘋果營養標簽的制定提供不同銷售時期蘋果多酚含量的依據,指導貯藏方式和時期的選擇,明確的消費信息,自2001年8月24日至2002年5月15日,由法國果蔬跨行業技術中心提供普通冷藏、氣調和超低氧方式下,不同銷售時期的嘎拉( malus , cv . gala )和金冠( m . cv . goldendelicious )為試材,根據蘋果食用習慣將果實分為果皮、果肉和果心二部分,利用硫解hplc和非硫解hplc定量分析世界主栽品種金冠和嘎拉果皮和果肉多酚物質含量,並對不同貯藏方式下和同一貯藏方式下的不同商業貯藏時期多酚物質含量作了比較。The a - transglucosidase was selectively modified by pcmb, me, edc, clac, acetyl acetone and nbs, and changes in the activities of the enzyme have been detected. the reaction of a - transglucosidase with pcmb, me, edc and clac resulted in a strong inhibition of the enzyme activities which decreased with the increase of modifier concentration. the acetyl acetone and nbs were found without inhibition effect
酚丙酮、小涅代唬拍酷亞胺剛b引等化學修飾劑對a葡萄糖轉苦酶的幾種氨基酸殘基進行選擇修飾,並測定其酶活力變化,結果表明: pcmb 、 me 、 edc 、 ciac能顯著抑制酶的活性,活力的下降與修飾劑的濃度有關,乙酚丙酮、 nbs白巾飾對酶的奪製作用不明顯。The md simulation data were analyzed in terms of average atomic positions, root mean square ( rms ) fluctuations, monomer - monomer interactions, hydrogen bond ( h - bond ) network, secondary structure, and so on. through the comparison, we found that when the system includes zn2 + ions and phenol, the stability of insulin hexamer is enhanced, but the conformational flexibility related to its biological activity is decreased. in addition, the insulin hexamer tends to dissociate in the absence of zn2 + and phenol
通過對這兩個模擬所得到的軌跡在原子的平均位置、方均根漲落、方均根偏差、單體之間相互作用、氫鍵網路、二級結構等方面進行的比較分析發現,對于包含鋅離子和苯酚的體系,胰島素六聚體的穩定性得到了增強,但其構象柔性卻受到了削弱;對不含鋅離子和苯酚的體系,胰島素六聚體的穩定性明顯減弱,構象柔性卻表現得較為突出,在這種情況下,胰島素六聚體還表現出解聚的傾向。In this thesis the in situ brilliant cresyl blue ( bcb ) dimer with weak fluorescence in the solution of anionic surfactant ( as ) sodium lauryl sulfonate ( sls ) was used as fluorescence probe. at the same time, the new method for the determination of bovine serum albumin ( bsa ) was built. the linear range was 0 - 7mg / l and the detection limit ( 3 o / k ) was 3. 66 10 - 3 mg / l, the r. s. d for the determination of 2. 00mg / l bsa was 2. 77 %
本論文以陽離子染料燦爛甲酚藍在陰離子表面活性劑十二烷基磺酸鈉存在下形成的現場弱熒光二聚體為熒光探針,建立了測定牛血清白蛋白的新方法,該法線性范圍為0 7mg / l ,檢測限為3 . 66 10 ~ ( - 3 ) mg / l ,對2 . 00mg / l幾的牛血清白蛋白平行測定8次,相對標準偏差為2 . 77 ,說明本法準確可靠。The re suits showed that during storage, the wi value of lotus epidermis were decreased, but not much change in inner lotus root ; polyphenol oxidase activity and phenols content were both showed increased and then de creased ; the fiber content of lotus root can affect the change of tender ; taken the factor of wi value, tender and decomposed rate into account, the quality of jn dawolong was the best
結果表明:貯藏過程中表皮白度逐漸下降,但藕肉白度變化不大;多酚氧化酶活性和多酚含量變化均呈現出先上升後下降的趨勢;纖維素含量對藕的脆度變化有一定的影響;綜合白度變化、脆度和腐爛率等因素來考察, 3個品種中以濟南大臥龍品質最優。Pcl ii had two mutations in nueleotide sequences and amino acid sequence compared with that of natural pcl ii. the effect of chemical modification of amino acid residues upon haemagglutination and mitogenic activity toward t - lymphocytes was investigated. modification of tyrosine ( 1 - acetylimidazole and 4 - nitrobenzenesulphonyl fluoride ) did not alter haemagglutination but decreased mitogenic activity by about one half
採用不同的方法對酪氨酸( tyr )進行了修飾:用勺r酚經基專一性試劑對硝基苯磺酞氟( nbsf )修飾pcln ,導致pcln促淋巴細胞有絲分裂活性大幅下降,表明巧r的酚經基對於此活性是必需的。The results show that the gel time of the resol prepared in this paper is much longer than that of resol catalyzed with normal alkali such as ammonia and it is more stable when temperature is under 160 ; while temperature exceeds 160, it cures very fast
結果表明,合成的酚醛樹脂中有大量醚鍵,常溫下它的凝膠時間很長,固化速度慢,溫度大於160后,醚鍵分解產生甲醛,促進固化,凝膠時間迅速減小,固化很快。分享友人
