facets of enzyme activity: D‐Fructose‐6‐phosphate aldolase (FSA) catalyzes the self‐aldol reaction of glycolaldehyde (GA) and its cross‐aldol addition to other aldehydes. As the affinity of GA for FSA as a donor is higher than that as an acceptor, cross‐aldol reactions are possible with good to poor aldehyde acceptors if the concentration of GA in the reaction is kept low.
酶活性的新方面:D-果糖-6-磷酸醛缩酶(FSA)催化乙醇醛(GA)及其与其他醛的交叉醛缩醛加成的自身醛醇缩合反应。由于GA对FSA作为供体的亲和力高于作为受体的亲和力,因此,如果将GA的浓度保持在较低水平,则醛类受体的良好或不良都可能发生交叉醇醛缩合反应。
