Cisvstrans and EvsZ isomers are geometric isomers that occur when substituents arelockedin position next to or opposite each other.This is seen in both double bonds for alkenes, and substituents on ring structures. Cis alkenes are on the same size, trans alkenes are on opposite sides. When t...

In isomerism: Cis and trans forms The examples presented so far have concentrated on the simplest organic molecules, the alkanes. However, stereoisomers crop up in many of the other structural types of organic chemistry. For example, in the alkenes, two versions of 2-butene exist. They are ...
Significantly, this protocol was successfully applied to the synthesis of cis‐ and trans‐alkenes in a highly stereoselective manner in a sequential one‐pot process.doi:10.1002/adsc.201500686Krishna, JonnadaKrishna?Reddy, Alavala GopiSatyanarayana, Gedu...

Alkenes like 1-butene and 2-butene exhibit constitutional isomerism, as they differ in the position of the double bond. Further, 2-butene exhibits stereoisomerism and exists as two distinct compounds differing in spatial arrangement. An isomer is calledcis-2-butene when the methyl groups are on...
There are several examples of peptides from venomous organisms that have cis peptide bonds, including contryphans (Pallaghy et al., 1999, 2000; Tong et al., 2007). Moreover, the coexistence of cis and trans isomers in regions of well-structured peptide toxins is well established. For exampl...
