Morphology

prolamine = proline + amine (opaque) = proline + amine

Although etymologically built from chemical terms ('proline' + 'amine'), the term is specialized and not derivable by an average B1 learner from its components.

Etymology

Prolamine is easy to remember because the name comes from the amino acid proline, which these grain proteins have a lot of, and the ending -amine, like the 'amino' parts of proteins. So, prolamine means a group of grain proteins rich in proline.
