Morphology

histamine = histidine (opaque) = hist + amine

The suffix 'amine' indicates a chemical compound, but the specific biological role of histamine is not derivable from 'histidine' alone.

Etymology

Histamine comes from histidine, a name built from the Greek histos meaning 'tissue', plus the chemical ending -amine. So, histamine is a chemical made in body tissues, which is why it causes swelling, itching, and other allergy reactions.
