  • cardiac
  • Due to abnormal cardiac development, patients with situs ambiguous usually develop right atrial isomerism consisting of 2 bilaterally paired right atria, or left atrial isomerism consisting of 2 bilaterally paired left atria. (wikipedia.org)
  • Right atrial appendage isomerism, also called right atrial isomerism, is a cardiac development defect in which the heart has bilateral right atria and atrial attachments in the muscle wall, as opposed to the normal right atrium and left atrium. (wikipedia.org)
  • Left atrial appendage isomerism, also called left atrial isomerism, is a cardiac development defect in which the heart has 2 bilateral left atria and atrial appendages in the muscle wall. (wikipedia.org)
  • Axial
  • cis -1,2- dimethylcyclohexane trans -1,2-dimethylcyclohexane Choose the best reason for your answer in part (a) This compound always has two groups in equitorial positions This compound always has two groups in an axial positions This compound has a minimum number of gauche interactions. (coursehero.com)
  • for instance: the C2 carbmethoxy in its biosynthesis end-product maintains the axial position, which can undergo epimerization via saponification to obtain the former in an equatorial position. (wikipedia.org)
  • chemistry
  • In food chemistry , medicinal chemistry and biochemistry , cis-trans isomerism is always considered. (wikidoc.org)
  • ISOMERISM INTRODUCTION This Powerpoint show is one of several produced to help students understand selected topics at AS and A2 level Chemistry. (slideplayer.com)
  • The concept of isomerism illustrates the fundamental importance of molecular structure and shape in organic chemistry. (studyvilla.com)
  • In 1870, he was chosen to succeed Georg Staedeler as Professor of General Chemistry at the Swiss Polytechnical Institute in Zürich, retaining also the position of full professor at the University of Zürich. (wikipedia.org)
  • enantiomers
  • Note that the eicosatetraenoate substrate loses one double bound to become an eicosatrienoic acid with three double bonds and that the epoxygenases typically form a mixture of R/S enantiomers at the attacked double bound position. (wikipedia.org)
  • for example, cytochrome P450 epoxidases attack DHA at the 16,17-double bond position to form two epoxide enantiomers, 16R,17S-EDP and 16S,1517-EDP. (wikipedia.org)
  • atom
  • Note that the position of the oxygen atom differs between the two: it is attached to an end carbon in the first isomer, and to the center carbon in the second. (wikidoc.org)
  • type
  • Let us consider an example to understand this type of isomerism. (pediaa.com)
  • That is, cell stimulation causes DHA to be released from the sn-2 position of their membrane-bound cellular phospholipid pools through the action of a Phospholipase A2-type enzyme and the subsequent attack of the released DHA by CYP450 epoxidases. (wikipedia.org)
  • differ
  • An example is when they differ by the position of a proton, such as in keto/enol tautomerism, where the proton is alternately on the carbon or oxygen. (wikidoc.org)
  • side
  • It is estimated that 5-10% of isomeric patients have mesocardia, in which the heart is positioned at the center of the thorax, 25-50% have dextrocardia, in which the apex of the heart is pointed toward the right side of the thorax, and 50 - 70% have levocardia, in which the apex of the heart is pointed toward the left side of the thorax.
