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. [2]
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 ...
Common changes in nucleotide analogues. Nucleic acid analogues are used in molecular biology for several purposes: Investigation of possible scenarios of the origin of life: By testing different analogs, researchers try to answer the question of whether life's use of DNA and RNA was selected over time due to its advantages, or if they were chosen by arbitrary chance; [3]
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 ...
An analog signal (American English) or analogue signal (British and Commonwealth English) is any continuous-time signal representing some other quantity, i.e., analogous to another quantity. For example, in an analog audio signal , the instantaneous signal voltage varies continuously with the pressure of the sound waves .

By Davide Barbuscia (Reuters) -President-elect Donald Trump's choice of Scott Bessent for Treasury secretary could lift some of the gloom that has pervaded the sagging U.S. government bond market ...
This form of the app store is often used by web developers to distribute apps that are not allowed in the Google Play Store; this may be due to an app allowing users wider access to the app system, or offering apps for "niche users" who choose to use only free and open-source software (F-Droid) or prefer to play indie games (Itch.io). Moreover ...
