An example of a technical term which may seem to the nonspecialist as a metaphor:
"Assembly of hemoglobin from newly synthesized globin chains requires the presence of chaperone proteins. To date, there are no well-described forms of anemia due to the failure of these assembly mechanisms. However, some mutations in the globin chains themselves appear to alter globin structure sufficiently that posttranslational formation of tetramers is impaired, producing a thalassemia-like syndrome."
