  2. Substrate (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Substrate_(chemistry)

    The term is used in a similar sense in synthetic and organic chemistry, where the substrate is the chemical of interest that is being modified. In biochemistry, an enzyme substrate is the material upon which an enzyme acts. When referring to Le Chatelier's principle, the substrate is the reagent whose concentration is changed.

  3. Substrate - Wikipedia

    en.wikipedia.org/wiki/Substrate

    Substrate (vivarium), the material used in the bottom of a vivarium or terrarium; Substrate (aquarium), the material used in the bottom of an aquarium; Substrate (building), natural stone, masonry surface, ceramic and porcelain tiles; Substrate (chemistry), the reactant which is consumed during a catalytic or enzymatic reaction

  4. Substrate (materials science) - Wikipedia

    en.wikipedia.org/wiki/Substrate_(materials_science)

    Substrate is a term used in materials science and engineering to describe the base material on which processing is conducted. Surfaces have different uses, including producing new film or layers of material and being a base to which another substance is bonded.

  5. Active site - Wikipedia

    en.wikipedia.org/wiki/Active_site

    In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of amino acid residues that form temporary bonds with the substrate, the binding site, and residues that catalyse a reaction of that substrate, the catalytic site.

  6. Turnover number - Wikipedia

    en.wikipedia.org/wiki/Turnover_number

    In chemistry, the term "turnover number" has two distinct meanings.. In enzymology, the turnover number (k cat) is defined as the limiting number of chemical conversions of substrate molecules per second that a single active site will execute for a given enzyme concentration [E T] for enzymes with two or more active sites. [1]

  7. Chemical specificity - Wikipedia

    en.wikipedia.org/wiki/Chemical_specificity

    Chemical specificity is the ability of binding site of a macromolecule (such as a protein) to bind specific ligands. The fewer ligands a protein can bind, the greater its specificity. The fewer ligands a protein can bind, the greater its specificity.

  8. Substrate presentation - Wikipedia

    en.wikipedia.org/wiki/Substrate_presentation

    Substrate presentation; A substrate (purple rectangle) is shown sequestered into a lipid domain (green lipids). The substrate's translocation to the disordered region (grey lipids) presents it to its enzyme (blue oval) where it is hydrolyzed. In molecular biology, substrate presentation is a biological process that activates a protein.

  9. Glossary of chemistry terms - Wikipedia

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
