摘要:植物血红蛋白是具有组氨酸侧链与血红素铁的配体结合位点可逆配位的植物六配位血红蛋白.它们介导电子转移反应,例如清除一氧化氮,并且在还原亚硝酸盐和羟胺方面特别有效.以前对植物血红蛋白的研究仅集中于这些反应的一次转换,而没有揭示结构特征,例如组氨酸六配位在整个催化循环中是否起着重要作用.这项工作的特点是使用两种不同的化学还原剂对羟胺还原成铵的稳态植物血红蛋白催化.K M和k Cat测量水稻植物红蛋白,马肌红蛋白,人神经球蛋白和水稻植物红蛋白突变蛋白的蛋白质值,其中六配位组氨酸已被亮氨酸替代(phyt:H73L).结果表明,由苄基紫精驱动的植物血红蛋白催化仅受远端组氨酸的解离速率常数的限制.这与单周转实验中的速率限制是一致的,并证明羟胺结合的动力学而不是植物血红蛋白的还原最终决定了反应.缺乏或具有更严格的六配位作用的其他蛋白质的催化作用要慢得多,这表明远端组氨酸和血红素铁之间键的容易可逆性需要底物结合和血红素铁还原.另一方面,2

摘要:Active materials of the invention contain at least one alkali metal and at least one other metal capable of being oxidized to a higher oxidation state. Preferred other metals are accordingly selected from the group consisting of transition metals (defined as Groups 4-11 of the periodic table), as well as certain other non-transition metals such as tin, bismuth, and lead. The active materials may be synthesized in single step reactions or in multi-step reactions. In at least one of the steps of the synthesis reaction, reducing carbon is used as a starting material. In one aspect, the reducing carbon is provided by elemental carbon, preferably in particulate form such as graphites, amorphous carbon, carbon blacks and the like. In another aspect, reducing carbon may also be provided by an organic precursor material, or by a mixture of elemental carbon and organic precursor material.

摘要:Implementations described herein generally relate to etheramine mixtures formed from a mixture of two or more multifunctional alcohol initiators, processes for the etheramine mixtures production, and its use as a curing agent or as a raw material in the synthesis of polymers. In one implementation, the process comprises mixing a polyol initiator having a melting point greater than a processing temperature and a polyol initiator having a melting point less than the processing temperature to form a polyol initiator mixture having a melting point less than the processing temperature, charging the polyol initiator mixture to an alkoxylation reaction zone, contacting the polyol initiator mixture with an alkylene oxide in the alkoxylation reaction zone to provide a mixture of alkoxylated precursor polyols and charging the mixture of alkoxylated precursor polyols to a reductive amination zone and reductively aminating the mixture of alkoxylated precursor polyols to form the etheramine mixture.

摘要:The present disclosure provides a process for the co-preparation of a polyetheramine and an alkylene amine mixture by aminating a liquid polyol initiator mixture comprising an alkoxylated alcohol and a solid high melting polyol. The polyetheramine and alkylene amine mixture may be used in a variety of applications, such as a curing agent for epoxy resin formulations or as a raw material in the synthesis of polyurea.

摘要:Amine functional polymers are prepared by polymerization of vinylamides with vinyl ester monomers. The resultant polymers are hydrolyzed under acid conditions and subsequently at least partially basified to the free-base amine. Byproduct salts are removed by precipitation or by extraction into an immiscible phase. The polymers made by this method are crosslinkable through reaction of the amine groups and are useful in high performance coatings, adhesives, binders and the like.
