Hemithioacetal是什么
WebThe model for the stereospecificity was further evaluated by a molecular modeling simulation with methylglyoxal hemithioacetal superimposed on the glyoxylate hemithioacetal. The mechanism of DJ-1 glyoxalase provides a basis for understanding the His residue-based stereospecificity. Database: ... WebHemithioacetal is synthesized from the reaction of thiol and aldehyde. It usually arises in the acid catalysis. They are an important intermediate in the preparation process of dithioacetals. Hemithioacetals are prepared by the reaction between aldehydes and …

Did you know?
In organic chemistry, hemithioacetals (or thiohemiacetals) are organosulfur compounds with the general formula R−CH(−OH)−SR’. They are the sulfur analogues of the acetals, R−CH(−OH)−OR’, with an oxygen atom replaced by sulfur (as implied by the thio- prefix). Because they consist of four … Meer weergeven Hemithioacetals are formed by the reaction of a thiol (R−SH) and an aldehyde (R−CH=O): Hemithioacetals usually arise via acid catalysis. They typically are intermediates in the … Meer weergeven Hemithioacetals ordinarily readily dissociate into thiol and aldehyde, however, some have been isolated. In general, these isolable hemithioacetals are cyclic, which disfavors dissociation, and can often be further stabilized by the presence of … Meer weergeven Glyoxalase I, which is part of the glyoxalase system present in the cytosol, catalyzes the conversion of α-oxoaldehyde (RC(O)CHO) and the thiol glutathione (abbreviated GSH) to S-2-hydroxyacylglutathione derivatives [RCH(OH)CO … Meer weergeven WebHemithioacetal.
