An MDL Molfile is a file format for holding information about the atoms, bonds, connectivity and coordinates of a molecule.. The molfile consists of some header information, the Connection Table (CT) containing atom info, then bond connections and types, followed by sections for more complex information.
Chemical similarity (or molecular similarity) refers to the similarity of chemical elements, molecules or chemical compounds with respect to either structural or functional qualities, i.e. the effect that the chemical compound has on reaction partners in inorganic or biological settings.
It most commonly refers to an index, called the Balassa index, introduced by Béla Balassa (1965). [1] In particular, the revealed comparative advantage of country c {\displaystyle c} in product/commodity/good p {\displaystyle p} is defined by:
The general definition of the elasticity of X with respect to Y is = % % , which reduces to = for infinitesimal changes and differentiable variables. The elasticity of substitution is the change in the ratio of the use of two goods with respect to the ratio of their marginal values or prices.
The careful choice of functional monomer is another important choice to provide complementary interactions with the template and substrates. [3] In an imprinted polymer, the cross-linker fulfills three major functions: First of all, the cross-linker is important in controlling the morphology of the polymer matrix, whether it is gel-type ...
If GL i = 1, there is a good level of intra-industry trade. This means for example the Country in consideration Exports the same quantity of good i as much as it Imports. Conversely, if GL i = 0, there is no intra-industry trade at all.
A ribosome is a biological machine that utilizes protein dynamics on nanoscales to translate RNA into proteins. Molecular recognition plays an important role in biological systems and is observed in between receptor-ligand, [16] [17] antigen-antibody, DNA-protein, sugar-lectin, RNA-ribosome, etc.
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
