Cis-trans Isomers of Vitamin
We have recently described the synthesis of rhodopsin in a solution containing four components: vitamin A, the precursor of the rhodopsin chromophore; opsin, the protein of rhodopsin; and liver alcohol dehydrogenase and cozymase, the enzyme and coenzyme which oxidize vitamin A to retinene (Hubbard and Wald, 1951). 1 This experiment was first performed with a fish liver 0il concentrate as the so...
متن کاملKinetics of the cis,cis to trans,trans isomerization of 1,1,2,2,5,5,6,6-octamethyl-1,2,5,6-tetrasilacycloocta-3,7-diene.
The kinetics of the ruthenium-promoted cis,cis to trans,trans isomerization of 1,1,2,2,5,5,6,6-octamethyl-1,2,5,6-tetrasilacycloocta-3,7-diene were investigated. Incubation of a ruthenium alkylidene complex, (Cy(3)P)RuCl(2)(==CHPh)Ru(p-cymene)Cl(2), in CD(2)Cl(2) for 5 days at 40 degrees C afforded a catalytically active ruthenium species that was shown to be responsible for promoting the isome...
متن کاملThe metabolism of cis- and trans-decalin.
1. The metabolism of cis- and trans-decalin in the rabbit has been investigated. 2. Both hydrocarbons were oxidized to racemic secondary alcohols and excreted as ether glucuronides in amounts equal to about 60% of the dose administered. The principal glucuronides were isolated as triacetyl methyl esters and as sodium salts. 3. cis-Decalin gave rise mainly to (+/-)-cis-cis-2-decalol, together wi...
متن کاملRelative stability of cis- and trans-hydrindanones.
The relative stabilities of several cis- and trans-hydrindanones were compared using both isomerization experiments and MM2 calculations. The generally believed rule that cis-hydrindanones are more stable than trans-isomers is applicable, but is not always true. This review introduces examples, mainly from studies in our laboratory, to explain these facts.
متن کاملTheoretical study of cis and trans structures
The large number of compounds that may exhibit cis-trans isomerism in inorganic chemistry illustrates, in terms of number of known examples, the progress of synthetic inorganic chemistry. In fact, from the studies conducted by Werner at the beginning of this century to the present day, a huge range of works involving this type of isomers can be found in the literature. 1-7 In the case of isomer...
