化学反应会受其所处微环境影响,因此不同分子间相互作用对反应进程的调控不容忽视。水溶液作为优良的反应介质,其应用常受到反应物溶解性差的限制。在水溶液中引入胶束或囊泡等两亲分子组装,可在一定程度上克服这种不足。这些均匀分散... 化学反应会受其所处微环境影响,因此不同分子间相互作用对反应进程的调控不容忽视。水溶液作为优良的反应介质,其应用常受到反应物溶解性差的限制。在水溶液中引入胶束或囊泡等两亲分子组装,可在一定程度上克服这种不足。这些均匀分散的动态组装,提供了有别于本体水溶液的微环境,以非共价的方式,将单体结合到其极性表面或疏水内核。通过加速特定的化学反应,并改变反应路径,这些超分子组装最终可提高目标产物的产量,达到与酶类似的催化效果。除实际应用外,这一概念或许也适用于生命起源相关的基础研究:早期地球可能存在包括氨基酸前体或磷脂前体在内的两亲分子组装,它们可能在生命起源化学中加速和指导化学反应。为详细阐明这一概念,本文综述了一些两亲分子组装介导化学反应的经典案例,具体包括水解反应、有机合成和共轭聚合物的合成等,最后对相关生命起源研究进行了讨论与展望。 展开更多

Everything in the universe occurs spontaneously. The first push of the universe signifies the capabilities of the universe in automatic movement, automatic reaction and change, automatic generation and development, automatic cognition and thinking, automatic organization, autonomous behavior and automatic control. Diverse substances, objects, thinking and life entities in the universe are all at automatic movement and change. There are 4 automatic reactions within the physical system: chemical reaction, nuclear fusion reactions, quark confinement reaction and weak interaction. Correspondingly, there are 4 similar reactions in organisms. The life entities include the life universe, organisms, human being, societies and artifacts. The automatic dynamic system exists within the life entities which has automatic cognition and thinking abilities. 4-season movement of life happens automatically. The automatic control of life movement includes 4-season control and thinking control whilst the later is an active type. The life universe forms under the automatic organization of the universe thinking. The social life entities are an active control system of thinking. The society has 5 automatic dynamic systems. The society is a life entity that automatically generates under the control and organization of thinking. The artifacts and the future artificial life are formed under the automatic organization and fabrication of human beings under the control of thinking. The earth is a life entity capable of making various biological molecules and 4-season mechanisms of organisms. The organism is created gradually during 4-season movement of earth and solar system. 展开更多
