21. Eszopiclone is the active dextrorotatory stereoisomer of zopiclone, and belongs to the class of drugs known as cyclopyrrolones. 22. Composed of an isotactic crystalline stereoisomer of polypropylene, Prolene sutures are intended to be durable and long lasting. 23. It is a synthetic monosaccharide, a stereoisomer ( mirror image ) of the natural compound D-deoxyribose. 24. In order to display optical activity, a fluid must contain only one, or a preponderance of one, stereoisomer . 25. Chiral auxiliaries are one of many strategies available to synthetic chemists to selectively produce the desired stereoisomer of a given compound. 26. The subsequent imine intermediate was treated with sodium borohydride, affording the wrong stereoisomer due to the F�rst-Plattner effect. 27. IMPase dephosphorylates the isomers of inositol monophosphate to produce inositol, mostly in the form of the stereoisomer , myo-inositol. 28. Commercial preparations contain only the ( R, R ) stereoisomer , which is the weakest isomer in terms of opioid activity. 29. Another interesting point is that it utilizes two amino acids uncommon in peptides : ornithine as well as the atypical stereoisomer of phenylalanine. 30. However, JMJD6 has recently been shown to be a lysyl hydroxylase which modifies an RNA splicing factor producing the ( 5S ) stereoisomer .
