1. (+/-)-2-, (+/-)-3- and 4-tert.-Butylcyclohexanone are reduced in the rabbit to secondary alcohols, which are excreted extensively conjugated with glucuronic acid. 2. The major metabolite of (+/-)-2-tert.-butylcyclohexanone is (+)-cis-2-tert.-butylcyclohexanol, which has been isolated from the urine as [(+)-cis-2-tert.-butylcyclohexyl beta-d-glucosid]uronic acid. The minor metabolite is (+)-t...

AIMS To isolate predominant ruminal bacteria that produce trans-10, cis-12 conjugated linoleic acid (CLA) from linoleic acid (LA). METHODS AND RESULTS Mixed bacteria from ruminal contents of a cow fed grain were enriched with DL-lactate and trypticase. They produced more trans-10, cis-12 CLA than those that were not enriched (7 vs 2 microg mg protein(-1), P < 0.05). Enrichments had an abundan...

1. The metabolism of cis-indane-1,2-diol, trans-indane-1,2-diol, indene epoxide and 2-hydroxyindan-1-one in rats has been studied. The substances were administered to the animals by subcutaneous injection. 2. The urine of the dosed animals was examined for the presence of free and conjugated cis- and trans-dihydrodiols, and for each compound it was possible to isolate both cis and trans forms o...

Erythrocytes serve as reservoirs for cis- and trans-epoxyeicosatrienoic acids (EETs). Incubation of rat red blood cells (RBCs) with cis- and trans-EETs produces threo- and erythro-dihydroxyeicosatrienoic acids, respectively. The V(max) of EET hydrolysis by rat intact RBCs (2.35 +/- 0.24 pmol/min/10(8) RBCs for 14,15-trans-EET) decreased by approximately 2 to 3-fold sequentially from 14,15-, 11,...

Synthesis and X-ray diffraction structures of cis and trans isomers of ruthenium and osmium metal complexes of general formulas (nBu4N)[cis-MCl4(NO)(Hind)], where M = Ru (1) and Os (3), and (nBu4N)[trans-MCl4(NO)(Hind)], where M = Ru (2) and Os (4) and Hind = 1H-indazole are reported. Interconversion between cis and trans isomers at high temperatures (80-130 °C) has been observed and studied by...

The title compound is a co-crystal of the cis and trans isomers, namely cis-bis-[1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato(1-)-κ(2)O,O']bis-(4-phenyl-pyridine N-oxide-κO)copper(II)-trans-bis-[1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato(1-)-κ(2)O,O']bis(4-phenyl-pyridine N-oxide-κO)copper(II) (2/1), [Cu(C(5)HF(6)O(2))(2)(C(11)H(9)NO)(2)]. In both isomers, the coordination geometry of the Cu(2+...

We have studied the disassembly and assembly of two morphologically and functionally distinct parts of the Golgi complex, the cis/middle and trans cisterna/trans network compartments. For this purpose we have followed the redistribution of three cis/middle- (GMPc-1, GMPc-2, MG 160) and two trans- (GMPt-1 and GMPt-2) Golgi membrane proteins during and after treatment of normal rat kidney (NRK) c...

A reversed-phase high-performance liquid chromatography method with diode array detection was developed for the determination of trans- and cis-resveratrol in red wines. Separation was achieved after direct injection by the use of a BDS Hypersil C18 column (250 × 4.6 mm) with gradient elution (solvent A: acetic acid 2%, solvent B: acetonitrile). Detection of trans- and cis-resveratrol was perfo...
