A structural analog, also known as a chemical analog or simply an analog, is a compound having a structure similar to that of another compound, but differing from it in respect to a certain component. [1] [2] [3] It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or ...
Functional analogs are not necessarily structural analogs with a similar chemical structure. [1] An example of pharmacological functional analogs are morphine, heroin and fentanyl, which have the same mechanism of action, but fentanyl is structurally quite different from the other two with significant variance in dosage.

In chemistry, a derivative is a compound that is derived from a similar compound by a chemical reaction.. In the past, derivative also meant a compound that can be imagined to arise from another compound, if one atom or group of atoms is replaced with another atom or group of atoms, [1] but modern chemical language now uses the term structural analog for this meaning, thus eliminating ambiguity.
Analog electronics, circuits which use analog signals Analog computer, a computer that uses analog signals; Analog recording, information recorded using an analog signal; Functional analog (electronic), a system that fulfills the same function as another; Structural analog (electronic), a system that has the same structure as another
Isolobal compounds are analogues to isoelectronic compounds that share the same number of valence electrons and structure. A graphic representation of isolobal structures, with the isolobal pairs connected through a double-headed arrow with half an orbital below, is found in Figure 1. Figure 1: Basic example of the isolobal analogy
The effect of the substrate analog can be nullified by increasing the concentration of the originally intended substrate. [6] There are also substrate analogs that bind to the binding site of an enzyme irreversibly. If this is the case, the substrate analog is called an inhibitory substrate analog, a suicide substrate, or a Trojan horse ...
Delightfully chewy gnocchi, often made with potatoes, is considered both a type of pasta and a type of dumpling — depending on who you ask. Can it also be a healthier, more nutritious ...
Transition state analogs (transition state analogues), are chemical compounds with a chemical structure that resembles the transition state of a substrate molecule in an enzyme-catalyzed chemical reaction. Enzymes interact with a substrate by means of strain or distortions, moving the substrate towards the transition state. [1]
