cis-trans

isomerization the conversion of the configuration of a ‘cis ’ isomer (see ISOMERISM), with similar atoms or groups on the same side of the molecule to a ‘trans ’ form, with the similar atoms or groups on opposite sides.

My intention in this article is to study the cis-trans isomerization and isomers formed during the thermal induction of methyl linolenate at 275[degrees]C.
It may be concluded that ppiases catalyze the peptidyl-prolyl cis-trans isomerization, the ratelimiting step of protein folding, which is essential for newly synthesized protein to get its correct functional form.
This could be explained in that the higher reaction temperature promoted cis-trans isomerization to enhance both the trans-1,4 and vinyl--1,2 units at the expense of the cis-1,4 isomer [23, 25], An increase in the reaction temperature also decreased the Mw of the Co/Nd-BR since the higher reaction temperature induced chain transfer, which led to a lower Mw with a broader MWD of the resulting BR [1, 23],
FKBP38 is a unique member of the FKBP family, in that it is membrane-anchored, and has peptidyl-prolyl cis-trans isomerase (PPIase) activity.
The reaction mechanism is similar to other palladium-catalysed cross-coupling reactions and it consists of oxidative addition, cis-trans isomerization, deprotonation (also called alkynylation), and reductive eliminantion steps.

It begins with a cis-trans isomerisation taking place at a double bond, a kind of rearrangement -- in an extremely unfavorable position in spatial terms, though, in which large side groups fight for space.
