Root Explanation

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.

Memory Tip

Think of 'blood' ('heme') and 'red' ('erythros') to remember that hemerythrin is a red protein related to blood.
