Definition of stereochemistry in English:

stereochemistry

noun ˌstɪərɪə(ʊ)ˈkɛmɪstriˌstɛrɪə(ʊ)ˈkɛmɪstri
mass noun
  • The branch of chemistry concerned with the three-dimensional arrangement of atoms and molecules and the effect of this on chemical reactions.

    Example sentencesExamples
    • Steroids have four rings fused together with a particular stereochemistry.
    • In terms of their chemical, pharmacological, kinetic and therapeutic properties, enantiomers and diasteriomers behave as distinct compounds, therefore stereochemistry should be a topic of major concern to all disciplines.
    • It serves as the introductory medicinal chemistry course and contains basic concepts such as the acid/base nature of drugs, functional groups, solubility, stereochemistry, receptor binding, and metabolism.
    • Computer-aided instruction augments learning in all topics, but most commonly in the areas of receptor theory and mechanism and stereochemistry.
    • There is a remarkable diversity in the stereochemistry of pheromones.
    • The purpose of subjecting the model to energy minimization is to refine reasonable stereochemistry produced by our motif modeling method.
    • Thus, in the third and last chapter of his professional life, he returned to stereochemistry.
    • The stereochemistry at each of its five chiral centres is pharmacologically critical.
    • The stereochemistry of the model was checked and all residues found to be in allowed conformations.
    • He synthesizes stereochemistry and crystallography with physiological optics, locating the enantiomorphic dislocation right between the eyes of the seeing subject.
    • By that time atomism had been extended from chemistry and the kinetic theory to offer explanations in stereochemistry, electro-chemistry, spectroscopy and so on.
    • Pasteur also formulated a law that states asymmetric molecules are always the product of life forces, which became the basis of a new branch of science, stereochemistry.
    • The stereochemistry of quinine is formidable: it has four chiral centres, and thus 16 stereoisomers - of which only one is the natural ingredient of cinchona bark.
    • Accordingly, both the stereochemistry of and the steric hindrance around the interactive hydroxyl group crucially affect the supramolecular structure of the self-assembled chromophores.
    • The final models display good stereochemistry.
    • Rather, it arises from a mixture of species, each one of which has reasonable stereochemistry.
    • The absolute stereochemistry was also determined in 1955 via chemical degradation of dihydrocodeinone.
    • Additionally, while adaptive code structure is unlikely to be an artifact of a stereochemically determined code, empirical evidence suggests that stereochemistry is not without a role.

    • Thus, their synthetic counterparts must also have the proper stereochemistry.
