Root Explanation

Myoglobin is formed from "myo-" (from Greek "musculus", meaning muscle) and "globin" (from Greek "globus", meaning sphere or ball). The word refers to a protein that is spherical in shape and found in muscle tissue, responsible for oxygen storage.

Memory Tip

Think of 'myo-' relating to 'muscle' and 'globin' indicating a 'spherical' protein — myoglobin is a muscle protein that stores oxygen.
