Interactive 3D animations of Diels-Alder reaction with E,Z diene - stereochemistry and mechanism for students studying University courses
Acylic dienes always react in the s-cisconformation. Butadiene normally prefers to be in the s-transconformation for steric reasons. However, it must adopt the unfavorable s-cisconformation, by rotating through its middle single bond to achieve a flat planar structure, before it reacts with the...
Structures of genistein and E2. Full size image To explore our working hypothesis further, we evaluated the cancer cell growth effects of dihydro-R in the presence of trans-R. Trans-R is capable of acting as both an estrogen and an antiestrogen [22–26], including non-genomic action [25...

The odds ratio of gene y’s expression in x+ vs x- cells was calculated as (d/c)/(b/a), and presented in the entry (x, y) of the heatmap. P-values were calculated using Fisher’s exact test in R (fisher.test()) and adjusted using the FDR method (p.adjust(method = ...
The behavior of the readily available cis - ( 1 ) and trans - ( 2 ) 4, 5-epoxy-2-pentenals toward classical cationic, anionic, and free radical initiators has been examined. Only the cationic polymerization of 1 gave soluble polymer of moderate molecular weights. This polymer possessed pre...
Thermodynamics of Gaseous Hydrocarbons: Ethane, Ethylene, Propane, Propylene, n‐Butane, Isobutane, 1‐Butene, Cis and Trans 2‐Butenes, Isobutene, and Neo... It is pointed out that the assumption of completely free internal rotation in the simpler hydrocarbon molecules is probably responsible for...
Molecular studies of gene regulation have classified regulatory interactions based on their effects in cis or trans, and the terms have been co-opted to describe particular types of regulatory elements. Consistent with the original definitions, cis regulatory elements have an allele-specific effect on...
trans-factors bind only to specific DNA sequence motifs (called cis-elements) [4]. In higher eukaryotes, many genes need to exhibit complex spatio-temporal expression patterns. The key to achieving such complexity is the combinatorial transcription regulation [5], i.e. different combinations of ...
