This hypothesis is agnostic regarding alkene configuration (i.e., Z or E). Consistent with this, here it is shown that certain class II diterpene cyclases, which normally convert (E,E,E)-geranylgeranyl diphosphate to 13E-trans-decalin bicycles, will also act upon (Z,Z,Z)-nerylneryl ...
How do you know if its cis or trans? Consider the longest chain containing the double bond: If two groups (attached to the carbons of the double bond) are on the same side of the double bond, the isomer is a cis alkene. If thetwo groups lie on opposite sides of the double bond, ...
SoZresembles“cis”andEresembles“trans”.(Note: they are not necessarily the same and do not always correlate: seeNote 2for an example of a cis alkene which is E . The E/Z system is comprehensive for all alkenes capable of geometric isomerism, including the cis/trans alkene examples abov...
By means of static and molecular dynamic DFT calculations, a simple olefin, like ethylene, is shown to be prone to the trans binding. Bearing in mind the higher reactivity of trans isomers in olefin metathesis, this insight helps to construct small alkene substrates with increased reactivity....

Trans alkenes have their substituents onopposite sides. Naming Cis/Trans Alkenes: Once you’ve identified cis/trans alkenes, naming them is fairly simple. 1) First, name the alkene using the tutorial linked below. 2) Then, simply add ‘cis’ or ‘trans’ in front of the name. ...
the first point of difference is decisive. When the high-priority substituents on both the carbon atoms of the double bond are on the same side, the alkene has aZconfiguration, whereas when the high-priority substituents are on the opposite side of the double bond, the alkene is said to ha...
