The choline-hexanoate IL increases the biphasic region of Pluronic solutions.
The fruity odours of wine are largely derived from the synthesis of esters and higher alcohols during yeast fermentation. The ATF1- and ATF2-encoded alcohol acetyltransferases of S. cerevisiae are responsible for the synthesis of ethyl acetate and isoamyl acetate esters, while the EHT1-encoded ethanol hexanoyl transferase is responsible for synthesizing ethyl caproate. However, esters such as t...
mnco2o4 (mno-co2o3) nanocomposite as a binary oxide has been successfully prepared by precipitation method using cobalt nitrate and manganese nitrate as the precursors and then characterized by scanning electron microscopy-energy dispersive micro-analysis (sem-edx) and x-ray diffraction (xrd) techniques. in this work, we report the hydrolysis kinetics reactions of semi mustard (chloroethyl ethy...
Experiments with labeled octanoic acid have shown that liver slices cleave the fatty acid to 2-carbon fragments which condense to form acetoacetate (l-3). The earlier findings (1, 2) of an equal distribution of the isotope between the carboxyl and carbonyl groups of acetoacetate after utilization of carboxyl-labeled octanoate indicate a random recondensation of 2-carbon fragments, while later f...
Short-chain esters play a significant role in the food industry as flavor and aroma constituents. Candida antarctica lipase B (CALB) is one of the most effective catalysts for organic synthesis. We constructed a CALB-displaying yeast whole-cell biocatalyst and applied it to esterification from caproic acid and ethanol. CALB was fused with the alpha-agglutinin C-terminal and the signal peptide o...
Reliable analytical methods able to establish wine authenticity and compliance with the origin/variety denomination are essential tools for safeguarding of consumers from fraud. In this work, we attempted discrimination certified monovarietal white wines produced in Abruzzo region (Central Italy) 2015 Trebbiano d’Abruzzo, Pecorino or Passerina grapes, all belonging variety. A preliminary sensor...
حفاظت از گروههای عاملی از مراحل اجتناب ناپذیر در سنتز آلی است، در این بین محافظت از گروههای آمینی بسیار حائز اهمیت است. روشهای متعددی از قبیل فرمیله کردن، استیله کردن، محافظت بصورت boc و موارد زیاد دیگری جهت محافظت از گروههای آمینی تاکنون گزارش شده است. از طرف دیگر توسعه و کاربرد کاتالیست ها و حلالهای دوستدار محیط زیست و مزایای واکنشهای بدون حلال همچون سرعت بالای واکنش، خالص سازی آسان، کاهش آلو...
In chick embryo hepatocytes, activation of acetyl-CoA carboxylase-alpha (ACCalpha) transcription by 3,5,3'-triiodothyronine (T3) is mediated by a cis-acting regulatory unit (-101 to -71 bp) that binds the nuclear T3 receptor (TR) and sterol regulatory element-binding protein-1 (SREBP-1). SREBP-1 directly interacts with TR on the ACCalpha gene to enhance T3-induced transcription. Here, we show t...
The safety of weed biological control depends upon the selection and utilization target by agent while causing minimal harm to non-target species. Selection species agents is determined presence behavioral cues, namely host secondary plant compounds that elicit oviposition feeding responses. Non-target same cues as found in may be at risk damage classical agents. Here we volatile constituents i...
