The repeating structural unit of most simple polymers not only reflects the monomer(s) from which the polymers are constructed, but also provides a concise means for drawing structures to represent these macromolecules. For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation.
Macromolecules are large molecules within your body that serve essential physiological functions. Encompassing carbohydrates, proteins, lipids and nucleic acids, macromolecules exhibit a number of similarities.For example, all except lipids are long chains made up of smaller building blocks, and digestion reduces the size of macromolecules so your body can absorb their component parts.acromolecules are large molecules within your body that serve essential physiological functions.
