IPA: /həˈmɛrɪθrɪn/
KK: /hɛˈmɛrɪθrɪn/
A type of protein that contains iron and helps some marine animals transport oxygen in their blood.
Hemerythrin is important for the oxygen transport in certain marine invertebrates.
Hemerythrin is formed from "heme" (from Greek "haima", meaning blood) and "erythrin" (from Greek "erythros", meaning red). The word refers to a red iron-containing protein found in some invertebrates that is involved in oxygen transport, thus relating to its blood-like color.
Think of 'blood' ('heme') and 'red' ('erythros') to remember that hemerythrin is a red protein related to blood.
