  2. Substrate (chemistry) - Wikipedia

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

    In the former sense, a reagent is added to the substrate to generate a product through a chemical reaction. 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.

  3. Substrate - Wikipedia

    en.wikipedia.org/wiki/Substrate

    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; Substrate (materials science), the material on which a process is conducted

  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. Substitution reaction - Wikipedia

    en.wikipedia.org/wiki/Substitution_reaction

    Substitution reactions in organic chemistry are classified either as electrophilic or nucleophilic depending upon the reagent involved, whether a reactive intermediate involved in the reaction is a carbocation, a carbanion or a free radical, and whether the substrate is aliphatic or aromatic. Detailed understanding of a reaction type helps to ...

  6. Active site - Wikipedia

    en.wikipedia.org/wiki/Active_site

    This approach has various purposes. Firstly, when substrates bind within the active site the effective concentration of it significantly increases than in solution. This means the number of substrate molecules involved in the reaction is also increased. This process also reduces the desolvation energy required for the reaction to occur. In ...

  7. 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.

  8. Polymeric surface - Wikipedia

    en.wikipedia.org/wiki/Polymeric_surface

    The science of polymer synthesis allows for excellent control over the properties of a bulk polymer sample. However, surface interactions of polymer substrates are an essential area of study in biotechnology , nanotechnology , and in all forms of coating applications.

  9. Substrate (aquatic environment) - Wikipedia

    en.wikipedia.org/wiki/Substrate_(aquatic...

    Substrate is the earthy material that forms or collects at the bottom of an aquatic habitat. It is made of sediments that may consist of: Silt – A loose, granular material with mineral particles 0.5 mm or less in diameter.
