Morphology

hematin = heme (opaque) = hemat + in

A specialized chemical name formed from the combining form 'hemat-' (blood) plus the chemical suffix '-in', which is unlikely to be inferred by average B1 learners.

Etymology

Hematin comes from the Greek root haima meaning 'blood' and the ending -in which is often used for a substance. So hematin is literally a 'blood' pigment, which is why it is a red, iron-containing substance made from hemoglobin and important for carrying oxygen.
