IPA: /ˈaɪs.oʊˌɛn.zaɪm/
KK: /ˈaɪsoʊˌɛnzaɪm/
A type of enzyme that has a different chemical structure but carries out the same function as another enzyme.
Isoenzymes can be found in different tissues of the body, performing similar roles in various biochemical processes.
Isoenzyme → It is formed from "iso-" (from Greek "isos", meaning equal or same) and "enzyme" (from Greek "enzymon", meaning leaven or ferment). The term refers to enzymes that have the same function but differ in structure, hence they are 'equal' in function but 'different' in form.
Think of 'iso-' meaning 'same' and 'enzyme' referring to a biological catalyst. This helps you remember that isoenzymes are different forms of enzymes that perform the same function.
