Polar Effect Exerted by Other Asymmetric Reactions,rabatsos et al. 1967), Felkin model (Chérest et al. 1968, Chérest and Felkin 1968), and other similar models are stereo-models for transition states that predict the stereochemistry of the reaction from the viewpoint of a steric effect.作者: 后來(lái) 時(shí)間: 2025-3-22 00:53
NAD(P)H as a Coenzyme,-glycosidic bond* acts as a shuttle redox reagent by interconverting between 1,4-dihydropyridine and pyridinium cation structures. The remaining part of the coenzyme mainly acts as the binding site for the apoenzyme.作者: 殘廢的火焰 時(shí)間: 2025-3-22 04:32
Enzymatic Reductions,1970a,b). The replacement of only one of the six amino acids by another one results in the appearance of steroid activity (Eklund et al. 1976). It seems that the steroid activity is an intrinsic property of the enzyme rather than the activity toward ethanol because the latter is not a normal bodily constituent (Damgaard 1981).作者: neologism 時(shí)間: 2025-3-22 10:39

Asymmetric Reduction in a Chiral Reaction Field,ihydropyridine moiety. The active site of the enzyme is surrounded by amino acid residues that form a chiral environment so as to achieve the asymmetric reduction of substrates. One of the attempts to mimic the system conveniently is to introduce one chirality into a 1,4-dihydropyridine derivative. 作者: DEMN 時(shí)間: 2025-3-24 08:17

Asymmetric Reduction in a Chiral Reaction Field,selective reduction should be achieved. One of the most effective NAD(P)H model compounds of this type is that which has a macrocyclic moiety in the molecule. The compound was designed with the intention of binding a substrate or a metal ion at the macrocyclic moiety.作者: 色情 時(shí)間: 2025-3-25 03:38
