WebFeb 27, 2024 · The development of highly efficient reactions at only the desired position is one of the most important subjects in organic chemistry. Most of the reactions in current organic chemistry are reagent- or catalyst-controlled reactions, and the regio- and stereoselectivity of the reactions are determined by the inherent nature of the reagent or … In biochemistry, the substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed. The substrate is transformed into one or more products, … See more In chemistry, the term substrate is highly context-dependent. Broadly speaking, it can refer either to a chemical species being observed in a chemical reaction, or to a surface on which other chemical reactions or microscopy are … See more Various spectroscopic techniques also require samples to be mounted on substrates such as powder diffraction. This type of diffraction, which involves directing high-powered X-rays at powder samples to deduce crystal structures is often performed with an See more In three of the most common nano-scale microscopy techniques, atomic force microscopy (AFM), scanning tunneling microscopy (STM), and transmission electron microscopy (TEM), … See more In atomic layer deposition, the substrate acts as an initial surface on which reagents can combine to precisely build up chemical structures.
