WebThin myofilaments are composed of 3 types of protein: ACTIN, TROPONIN, and TROPOMYOSIN. The actin molecules (or G-actin as above) are spherical and form long chains. Each thin myofilament contains two such chains that coil around each other. TROPOMYOSIN molecules are lone, thin molecules that wrap around the chain of ACTIN.
