Isoelectronicity is a phenomenon observed when two or more molecules have the same structure (positions and connectivities among atoms) and the same electronic configurations, but differ by what specific elements are at certain locations in the structure. For example, CO, NO +, and N 2 are isoelectronic, while CH 3 COCH 3 and CH 3 N = NCH 3 are ...
For example, the replacement of a hydrogen atom with a fluorine atom at a site of metabolic oxidation in a drug candidate may prevent such metabolism from taking place. Because the fluorine atom is similar in size to the hydrogen atom the overall topology of the molecule is not significantly affected, leaving the desired biological activity ...

In drug discovery, either a large series of structural analogs of an initial lead compound are created and tested as part of a structure–activity relationship study [5] or a database is screened for structural analogs of a lead compound. [6] Chemical analogues of illegal drugs are developed and sold in
The majority of pre-packaged foods are required to list all ingredients, including all food additives such as color; however section B.01.010 (3)(b) of the Regulations provide food manufacturers with the choice of declaring added color(s) by either their common name or simply as "colour". [24] The maximum permitted level of tartazine is 300 ppm ...
The following is a list of notable proteins that are produced from recombinant DNA, using biomolecular engineering. [1] In many cases, recombinant human proteins have replaced the original animal-derived version used in medicine.
Trypsin inhibitor is present in various foods such as soybeans, grains, cereals and various additional legumes. [10] The main function of trypsin inhibitors in these foods is to act as a defense mechanism. By having this harmful component wild animals learn that any food that contains trypsin inhibitor is a food to avoid.
