cis 和 trans 是顺反异构体的概念，这类异构体属于立体异构的一种。顺反异构源于分子中双键不能自由旋转的特性，常见于烯烃类化合物。这类异构体根据双键两侧的原子或基团分布不同，可以分为顺式异构体和反式异构体。顺式异构体是指两个相同原子或基团位于双键同一侧的化合物。在化学结构中，我们可以...
回答者:网友 cis 和 trans是顺反异构体。我们知道,同分360问答异构体除了包括碳链异构、官能团位置异构、官能团异类异构还包括顺反异构、旋光异构等。cis 和 trans就为顺反异构。顺反异构:立体异构的一种,由于双键不能自由旋误剧胜转引起的,一般指烯烃的双键顺式异构体:两个相同原子或基团在双键同一侧的为顺式...
"In cis"是拉丁语，意为 "在此段的这一侧"。这个术语用于描述同一侧的两个物体或分子之间的相互作用。在化学中，该术语被用于描述两个双键在同一侧的分子。在生物学中，in cis常用于描述两个蛋白质在同一侧的受体和信号分子之间的相互作用。这种相互作用通常比in trans相互作用...

Differences in gene expression are central to evolution. Such differences can arise from cis-regulatory changes that affect transcription initiation, transcription rate and/or transcript stability in an allele-specific manner, or from trans-regulatory ch

We have examined the photobehavior of a set of isomers of 2-pyranone-annulated stilbenes (6-styrylcoumarin1, 7-styrylcoumarin2, 4-methyl-6-styrylcoumarin3, and 4-methyl-7-styrylcoumarin,4) in their crystalline phases. While thecisisomers of1–3undergocis→transphotoisomerizations in the solid...
Large-scale brain network interactions have been described between trans- and cis-gender binary identities. However, a temporal perspective of the brain's spontaneous fluctuations is missing. We investigated the functional connectivity dynamics in transm
