facets of enzyme activity: D‐Fructose‐6‐phosphate aldolase (FSA) catalyzes the self‐aldolreaction 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‐aldolreactions are possible with good to poor aldehyde acceptors if the concentration of GA in the reaction is kept low.

Prebiotic sugars: An investigation of carbonyl migration and epimerization, proceeding down the entire carbon chain of tetrose sugars (d-erythrose and d-threose) in aqueous media, and ultimately leading to a mixture of d-erythrulose, rac-erythrulose and rac-tetroses arising from the above reactions, is presented in this study.
