The title compound, C(26)H(24)FNO(3), is a critical inter-mediate of a selective and competitive inhibitor of the enzyme 3-hy-droxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase. Inter-molecular N-H⋯O hydrogen bonding generates a chain along [give direction] that is the dominant inter-action in the crystal packing. Inter-molecular C-H⋯O inter-actions are also observed.
In this scheme, the racemase involves a rearrangement of the hydrogen about the asymmetrical carbon (6,7), while the mutase reaction involves an intramolecular migration (8, 9) of the thioester group (l&12). Two approaches are available to determine the source of the hydrogen that arises on carbon 3 of succinyl-CoA as a result of methylmalonyl-Coil mutase action. The first or indirect approach,...
The aim of this study was to investigate the possible existence and magnitude of stable carbon isotope discrimination by human 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR). The catalytic portion of HMGR was expressed and purified. The reaction product mevalonate was lactonized and extracted from the reaction mixture by a solid-phase extraction protocol. Stable carbon isotope ratios of...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
تاثیر آموزش تفکر انتقادی به شیوه مباحثه بر روی مهارت درک متن یادگیرندگان انگلیسی به عنوان زبان خارجی
the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
Flash Boiling atomization is one of the most effective means of generating a fine and narrow-dispersed spray. Unless its complexity its potential has not been fully realized. In This Paper, a three dimensional chamber has been modeled with a straight fuel injector. Effect of Flash Boiling has been investigated by computational fluid dynamics (CFD) techniques. A finite volume approach with the ...
