THE CHEMISTRY OF LIFE !! ATOMS, MOLECULES, AND …
www.uc.eduAtoms are the smallest stable units of matter. They can combine to form molecules with complex shapes. The atomic components and unique three-dimensional shape of a particular molecule determine its function. For example, complex protein molecules form filaments that produce the contractions of muscle cells in the heart.

Monomers are atoms or small molecules that bond together ...
web.pdx.eduMonomers are atoms or small molecules that bond together to form more complex structures such as polymers. There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides. Each of these monomer types play important roles in the existence and development of life, and each one can be synthesized abiotically.
