IPA: /ˈaɪsəˌmaɪzd/
KK: /ˈaɪsəˌmɪraɪzd/
Changed from one form to another that has the same chemical formula but a different arrangement of atoms.
The isomerized compound has different properties than its original form.
Isomerized → It is formed from "iso-" (meaning equal or same) and "mer" (from Greek "meros", meaning part) and the suffix "-ize" (meaning to make or to cause to be). The word "isomerized" refers to the process of changing a compound into another compound that has the same molecular formula but a different arrangement of atoms, thus making it a different part or form of the same substance.
Think of 'equal parts' ('iso-') being rearranged ('mer') to create a new form, which is what isomerized means.
