1Biology The dissolution of cells by lysins or enzymes from different species.
2Chemistry The breakdown of a compound into oppositely charged ions.
Example sentencesExamples
However, heterolysis is the main process for generating the isolated phenoxy radicals.
The energy required to break a given bond of some specific compound by heterolysis.
In accordance with this embodiment, the dye cation formed from heterolysis of the leuconitrile color former is bleachable at high doses of actinic radiation.
By mutations that place the histidine in a similar distance to the heme as in the active site of peroxidases, compound I of myoglobin has been observed, probably owing to an increased rate of heterolysis.
This showed the reaction to proceed via the formation of a ring-closed carbonium ion-intermediate at C1, and the rate-determining step to be the subsequent heterolysis of the C1 - O bond.
The conclusion was that homolysis and heterolysis did not take place; furthermore the paper summarized the chemistry of peroxynitrite known at that time.

heterolytic
adjective
The more common way is ‘heterolytic cleavage’ where one of the atoms retains both of the bonding electrons, and the other takes none.
Example sentencesExamples
The C - 8 position of guanine in DNA is the major site of reaction of the potent electrophile acetoxy-IQ, which forms a nitrenium ion, by heterolytic loss of the acetoxy group, as the ultimate DNA-reactive species.
The two different species are formed by homolytic or heterolytic O-O bond cleavage and H-atom abstraction, respectively.
Reactions 4 and 5 involve homolytic and heterolytic O-O bond cleavage of the peroxides, respectively, and in most cases, the two pathways can be identified by product analysis.
For example, when malachite green is irradiated with UV light of 225-300 nm, heterolytic cleavage of the C-R bond occurs, and a charged photoproduct is formed with minimal changes in geometric conformation.
