Influences of hydrogen sulfide , element sulfide , mercaptan , sulphuring ether , disulfide individually on silver strip corrosion of jet fuel , and of element sulphur coexisting with other sulfide on silver strip corrosion of jet fuel were studied 考察了硫化氫、元素硫、硫醇、硫醚、多硫化物等單獨存在時對噴氣燃料銀片腐蝕的影響;同時研究了元素硫與其它硫化物以不同濃度混合時對噴氣燃料銀片腐蝕的影響。

Huwentoxin - i ( hwtx - i ) is a polypeptide neurotoxin isolated from the crude venom of chinese bird spider selenocosmia huwena . its molecular weight is 3750 dalton . the toxin contains 33 amino acid residues and three disulfide bonds 虎紋捕鳥蛛毒素- ( huwentoxin - )是從虎紋捕鳥蛛selenocosiahuwena粗毒中分離得到的一種多肽類神經毒素,分子量為3750 ,由33個氨基酸殘基組成,含三對二硫鍵。

Then formation of three disulfide binds of hw - ma and rgd - hw was monitored by reversed - phase hplc using air oxidization or reduced and oxidized glutathione respectively . the synthetic peptide was purified by double reversed - phase hplc 用hplc分離純化,得到的合成產物經質譜鑒定, hw一ma和rgd一hw粗膚的實際測定值和復性后突變體理論值都一致,證明合成和氧化復性是成功的。

Made of high - speed mixing polytetrafluoethylene resin and a certain volume of filling agent ( such as carbon fiber , graphite , molybdenum disulfide , glass fiber and bronze powder etc . ) shaped by moulding then through high heat sintering 用聚四氟乙烯樹酯與一定量的填充劑(如:碳纖維、石墨、二硫化組、玻璃纖維、青銅粉等)經高速混合均勻后用模塑成型經高溫燒結制成。

The trials of nr / r single - dimensional sds - page and nr / r two - dimensional sds - page proved that cml had no disulfide bond . edta inhibited the agglutinate activity of cml and a small part of cml recovered its agglutinate activity after removing the edta 在ph7 . 0 、 ph5 . 0的緩沖體系中,用edta去除cml分子中金屬離子的實驗表明edta對cml的凝血活性具有抑制作用。

Studies of inactivation of a - transglucosidase by chemical modification demonstrated that cys , asp ( glu ) and his residues were indispensable groups of the a - transglucosidase . partial disulfide bonds were the function of this enzyme 因止,認為cys 、 asp (以)和川s殘基為q葡萄糖轉苦酶的必需基團,部分二硫鍵對保護酶的催化功能是必需的。

Disulfide bridge in proteins , a covalent bond formed between the sulfhydryl ( - sh ) groups of different cysteine molecules . such bridges are important in stabilizing the tertiary structure of peptides and proteins 二硫橋:在蛋白質中兩個半胱氨酸殘基的兩個巰基之間形成的共價鍵。這樣的結構對于維持多肽和蛋白質三級結構的穩定有重要的作用。

The changes of cd and agglutinate activity of cml in different ph , temperature , concentration of guanidiniumhydrochloride indicated that cml had a comparatively stable structure despite of its lack of disulfide bond and having so much 3 - fold 測定不同ph 、溫度及不同濃度鹽酸肌中的cml的圓二色譜以及在這些條件下cml凝血活性的變化。

The main results are : ( 1 ) the tof - ms and rempi spectrum of carbon disulfide are detected . ( 2 ) the tof - ms of carbon disulfide is identified ; the rempi spectra of c , s , cs and cs2 are analyzed ( 3 )通過對實驗測定的tof質譜和分質量的rempi譜的分析,討論了二硫化碳分子的多光子共振電離一解離通道以及碎片的解離通道。

According to the sequences similarity and the same disulfide linkage of hwtx - v family with other toxins with known 3d structures , we can postulate that hwtx - v may belong to ick ( inhibitory cysteine knot ) motif 從這些同源序列的二硫鍵的結合方式看來, hwtx一v和mhwtx一v很可能屬( 1nhibitorycysteineknot ) ick結構模體。
