Source: Webster's dictionaryA nonnative isomer of some peptide groups can disrupt the conformational folding significantly, either slowing it or preventing it from even occurring until the native isomer is reached. Source: Internet
A mer isomer can be considered as a combination of a trans and a cis, since it contains both trans and cis pairs of identical ligands. Source: Internet
As an example of a geometric isomer due to a ring structure, consider 1,2-dichlorocyclohexane: Comparison of physical properties Cis and trans isomers often have different physical properties. Source: Internet
An isomer of tretinoin, isotretinoin is also used orally (under the trade names Accutane and Roaccutane), generally for severe or recalcitrant acne. Source: Internet
A nuclear isomer may also be called a " meta -state", meaning the system has more internal energy than the " ground state " (the state with the lowest possible internal energy), making the former likely to decay into the latter. Source: Internet
All "stable" isotopes (stable by observation, not theory) are the ground states of nuclei, with the exception of tantalum-180m, which is a nuclear isomer or excited state. Source: Internet
