Trans-10, cis-12 Conjugated Linoleic Acid
Conjugated linoleic acids (CLA) are a group of linoleic acid isomers having double bonds in conjugated position, i. e. the double bonds are separated by one single bond. Two of the isomers: cis-9, trans-11 (c9, t11) and trans-10, cis-12 (t10, c12) CLA, have been shown to have biologically interesting properties. The c9, t11 CLA has been reported to have anticancer, antidiabetic and anti-inflamm...
متن کاملSome photophysical studies of cis- and trans-urocanic acid.
Urocanic acid, an important human skin chromophore, undergoes a variety of photochemical transformations when exposed to the near-UV portion of sunlight and natural daylight, the principal reaction being the transformation from the stable trans- or (E)-form of the chromophore (trans-UA) to the biologically active cis- or (Z)-form (cis-UA), which is claimed to induce immunosuppression linked to ...
متن کاملIdentification and quantitation of all-trans- and 13-cis-retinoic acid and 13-cis-4-oxoretinoic acid in human plasma.
Human plasma was analyzed by high performance liquid chromatography for the presence of retinoic acid and 4-oxoretinoic acid isomers. Peaks that coeluted with the reference compounds all-trans-retinoic acid, 13-cis-retinoic acid, and 13-cis-4-oxoretinoic acid were routinely observed in human plasma. These retinoids were unequivocally identified by the following methods: comigration with referen...
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 کاملTrans-cis isomerization and the blue phases.
A new class of photoactive chiral liquid crystals based on a photoactive nematic host material and a photoinactive chiral dopant was utilized to investigate the behavior of the blues phases when trans-cis isomerization is induced. While the general behavior follows what has been observed in the cholesteric phase, the sensitivity of the blue phases to external parameters causes different behavio...
