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 کاملAnalytical in-house method validation for determination of permethrin (trans & cis isomers), methyl paraben, propyl paraben and BHT
Background: Permethrin is a drug used to cure pediculosis known as head lice. This drug is available in two forms: 1) permethrin topical cream 5%, 2) permethrin shampoo 1%. The aim of this study was to find a method and define the simultaneous cis and trans isomers for permethrin, methyl paraben, propyl paraben and butylated hydroxytoluene in topical cream 5% using the method high-performance l...
متن کاملIncorporation of dietary cis and trans isomers of octadecenoate in lipid classes of liver and hepatoma.
Groups of rats bearing Morris minimal deviation hepatoma 7288CTC were fed a fat-free diet supplemented with either 0.5% safflower oil (diet A), 15% safflower oil or free acids (diets Band C), or 15% safflower oil or free safflower fatty acids (diet D) for 4 weeks. A group of normal rats was also fed diet D. Triglycerides, cholesteryl esters, phosphatidylcholines, and phosphatidylethanolamines i...
متن کاملThe Metabolism of 14C-Labeled cis and trans Isomers of Octadecenoic and Octadecadienoic Acids
The physical properties of common unsaturated fatty acids are altered when they are converted to their geometric isomers. For example, isomerization of the naturally occurring cis acid, oleic acid, to its trans form, elaidic acid, raises its melting point by 30”, changing it from a liquid to a solid at body temperature. Theoretically, such isomeric pairs might be expect.ed to differ in their me...
متن کاملSolid-state compounds of stereoisomers: cis and trans isomers of 1,2-cyclohexanediol and 2,3-tetralindiol.
The phases of 1,2,3,4-tetrahydro-2,3-naphthalenediol (or 2,3-tetralindiol) and of 1,2-cyclohexanediol have been investigated. The structure of a very stable 1:1 compound (or co-crystal) of the cis and trans isomers of 2,3-tetralindiol, the existence of which has been known for nearly a century, has finally been determined. No evidence of any analogous compound between the cis and trans isomers ...
