transIsomerie

Trans isomerie, also known as trans Isomerism or trans configuration, is a type of stereoisomerism observed in organic chemistry. It occurs when two identical or similar groups are attached to opposite sides of a double bond or a ring structure. This arrangement results in molecules with the same chemical formula but different spatial arrangements of atoms. In the context of double bonds, specifically alkenes, the term "trans" indicates that substituents are on opposite sides of the carbon-carbon double bond. This is in contrast to "cis" isomers where the substituents are on the same side. Trans isomers generally have higher melting points and lower boiling points than their cis counterparts due to more efficient packing in the solid state. They can also exhibit different physical properties such as solubility and reactivity. Trans isomerie is particularly important in biological systems, for example, in fatty acids, where the trans configuration can lead to different physiological effects compared to their naturally occurring cis isomers.
