  2. Isoelectronicity - Wikipedia

    en.wikipedia.org/wiki/Isoelectronicity

    Isoelectronicity is a phenomenon observed when two or more molecules have the same structure (positions and connectivities among atoms) and the same electronic configurations, but differ by what specific elements are at certain locations in the structure. For example, CO, NO +, and N 2 are isoelectronic, while CH 3 COCH 3 and CH 3 N = NCH 3 are ...

    en.wikipedia.org/wiki/Structural_analog

    In drug discovery, either a large series of structural analogs of an initial lead compound are created and tested as part of a structure–activity relationship study [5] or a database is screened for structural analogs of a lead compound. [6] Chemical analogues of illegal drugs are developed and sold in

    en.wikipedia.org/wiki/Food_engineering

    Although food engineering is a relatively recent and evolving field of study, it is based on long-established concepts and activities. [1] The traditional focus of food engineering was preservation, which involved stabilizing and sterilizing foods, preventing spoilage, and preserving nutrients in food for prolonged periods of time. [5]

    Bioreactor. Biochemical engineering, also known as bioprocess engineering, is a field of study with roots stemming from chemical engineering and biological engineering.It mainly deals with the design, construction, and advancement of unit processes that involve biological organisms (such as fermentation) or organic molecules (often enzymes) and has various applications in areas of interest ...

  8. List of cocaine analogues - Wikipedia

    en.wikipedia.org/wiki/List_of_cocaine_analogues

    For example, the end product of cocaine biosynthesis contains an axial C2-carbomethoxy moiety which readily undergoes epimerization to the equatorial position via saponification. For any 2D structural diagrams where stereochemistry is not indicated, it should be assumed the analogue depicted shares the stereochemical conformation of R -cocaine ...

    en.wikipedia.org/wiki/Bioisostere

    For example, a chloride -Cl group may often be replaced by a trifluoromethyl -CF 3 group or by a cyano -C≡N group. Depending on the particular molecule used, the substitution may result in little change in activity, or either increased or decreased affinity or efficacy - depending on what factors are important for ligand binding to the target ...
