The Structure and Function of Macromolecules Part II: Proteins & Nucleic Acids The FOUR Classes of Large Biomolecules All living things are made up of four classes of large biological molecules: Structure.

Muscles and Muscle Fiber. Structure.     . Muscles are composed of many fibers that are arranged in bundles called FASCICLES. Individual muscles are separated by FASCIA, which also forms tendons. Here are major advantages of steel structure building including costing, safety, designs and uses.
