In chemistry, the term substrate is highly context-dependent. [1] 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 performed. In the former sense, a reagent is added to the substrate to generate a product through
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.
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
Organisation of enzyme structure and lysozyme example. Binding sites in blue, catalytic site in red and peptidoglycan substrate in black. (In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
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.

3,3′,5,5′-Tetramethylbenzidine or TMB is a chromogenic substrate used in staining procedures in immunohistochemistry as well as being a visualising reagent used in enzyme-linked immunosorbent assays . [1] TMB is a white solid that forms a pale blue-green liquid in solution with ethyl acetate.
Conversely, an example of a protein-ligand system that can bind substrates and catalyze multiple reactions effectively is the Cytochrome P450 system, which can be considered a promiscuous enzyme due to its broad specificity for multiple ligands. Proteases are a group of enzymes that show a broad range of cleavage specificities.
In chemistry, a leaving group is defined by the IUPAC as an atom or group of atoms that detaches from the main or residual part of a substrate during a reaction or elementary step of a reaction. [1] However, in common usage, the term is often limited to a fragment that departs with a pair of electrons in heterolytic bond cleavage. [2]
