Difference Between Cis and Trans Fat

Cis–trans isomers are stereoisomers, that is, pairs of molecules which have the same formula but whose functional groups are in different orientations in three-dimensional space. Cis-trans notation does not always correspond to E–Z isomerism, which is an absolute stereochemical description. See more Cis–trans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in chemistry that concerns the spatial arrangement of atoms within molecules. The prefixes "cis" and "trans" are from … See more Cis–trans isomerism can also occur in inorganic compounds, most notably in diazenes and coordination compounds.

As a recap, cis and trans stereoisomerism depends on whether two identical alkyl groups on the c=c bond are on the same or opposite sides of that double bond: The cis and trans approach works only if two identical groups are connected to … Bei einer Doppelbindung lassen sich die cis- und trans-Isomere ineinander umwandeln (cis-trans-Interkonversion). Hierzu ist eine vorübergehende Auflösung der π-Bindung nötig, was meist photochemisch oder bei höheren Temperaturen erfolgt. Der Prozess der photochemischen Interkonversion erfolgt hierbei anhand elektronischer Anregung in den Singulett Spinzustand. Die nicht verdrillte Molekülstruktur ist hierbei sowohl sterisch, als auch energetisch benachteiligt. E…
