Conjugated Linoleic acid (CLA) is a term which refers to a mixture of positional and geometric isomers of linoleic acid . The natural CLA resources are mainly from meat and milk products of ruminants where c9, t11-CLA is the predominant isomer. CLA has attracted considerable attention due to its physiological activities, such as the reduction of cancer incidence , a decrease in body fat content , profitable effects on atherosclerosis , and improvement of immune system . CLA can be chemically synthesized by the dehydration of hydroxyl fatty acids and alkali isomerization or photoisomerization of unsaturated fatty acids or linoleic-rich oil. Low yields, extensive purification steps, and inseparability of isomers limit commercial use of most chemicals methods . Hence, biotechnology presents new alternatives to traditional lipid manufacturing methods. CLA production by fermentation and utilization of microorganisms containing linoleic acid may be a viable alternative to organic synthesis. A great advantage of biocatalysis by whole microorganisms or purified enzymes is that there is high specificity for the isomers that are produced. The aim of our present research work is to develop an efficient method to produce a safe food supplements with high CLA content by exploiting the use of enzymes extracts which has not achieved much attention e.g. propionibacteria with unsaturated fatty acids or linoleic-rich oil (Cotton seed, sunflower, olive oil) as a substrate.

Chemoenzymatic synthesis of chiral hydroxymethyl cycloalkenols Şenocak, Deniz; Demir, Ayhan Sıtkı; Department of Chemistry (2004) Chiral cyclic alkenols with hydroxymethyl functionality are important structural units in many biologically active natural compouds such as prostaglandins, sesquiterpene antiviral agents, pentenomycins, xanthocidin, sarkomycin, etc. 1,3-cycloalkanediones are converted into bicyclic polyoxo derivatives with formaldehyde and trioxane in the presence of Lewis acid. Selective oxidation of the bicyclic compounds by using manganese(III)acetate followed by enzyme-catalyzed kinetic resolution afforded chiral bicycl...
Isomerization of 4,6-DinitrobenzofuroxanA DFT Study Türker, Burhan Lemi (2011-01-01) The present study concentrates on the isomerization process of 4,6-dinitrobenzofuroxan and the monoionic forms of its bicyclic isomers. The ionic forms shed some light on the stability of those isomers in an ionizing electric field or static charging. To achieve the goals of the study, certain density functional theory (DFT) calculations have been carried out at the restricted and unrestricted levels of B3LYP using 6-31G(d) and 6-311+G(d,p) basis sets. The stabilities and some other quantum chemical propert...
Chemoenzymatic synthesis of alpha(1)- and alpha-acetoxylated cyclic ketones Tanyeli, Cihangir; Akhmedov, M (Elsevier BV, 2004-06-07) alpha,beta-Unsaturated and saturated cyclic ketones were selectively oxidized at the alpha'- and alpha-positions using Mn(OAc)(3) and Pb(OAc)(4), respectively, resulting in high chemical yields. The resultant racemic alpha'- and alpha-acetoxylated substrates were resolved into corresponding enantiomerically enriched alpha'- and alpha-hydroxylated and acetoxylated compounds with 96-98% ee via PLE hydrolysis. The absolute configurations of alpha'-acetoxy-alpha,beta-unsaturated cyclic ketones were determined b...
Viscoelastic properties of reactive and non-reactive styrene-maleic anhydride olefinic blends Bayram, G; Yılmazer, Ülkü; Xanthos, M (2000-05-11) Reactive blends of styrene-maleic anhydride (SMAH) with polyethylene/methyl acrylate/glycidyl methacrylate (PE-F) and non-reactive blends of SMAH with polyethylene/methyl acrylate (PE-NF) were produced and characterized in terms of morphology and viscoelastic properties in order to understand the reaction characteristics between anhydride/epoxy functional groups. Storage modulus, G', loss modulus, G " and complex viscosity, eta* of reactive blends at 25 % and 50 % PE-F were higher than those of non-reactive...
Enantioselective direct aldol reactions promoted by phosphine oxide aziridinyl phosphonate organocatalysts Doğan, Özdemir (2015-12-15) A series of phosphine oxide based chiral Lewis bases were screened as organocatalysts for silicon tetrachloride mediated direct asymmetric aldol reactions between cyclohexanone and various aromatic aldehydes. One of the phosphine oxide-aziridinyl phosphonate POAP-A Lewis bases formed the aldol products in up to 75% yield and with 65% ee.
