About the Introduction to Food Macromolecules Virtual Lab Simulation

Macromolecules are very large molecules created by the polymerization of small units called monomers. Most of the macromolecules are present in everyday life, for instance in food.

Learn about biological macromolecules

There are several types of biological macromolecules: Carbohydrates, Proteins, Lipids and Nucleic acids. All macromolecules, except lipids, are polymers. A polymer is a long molecule composed of chains of monomers. Monomers are small molecules that serve as building blocks of polymers. In addition, there are also oligomers in nature. Oligomers are molecular complex composed of a few monomer units, instead of the theoretical unlimited nature of polymers. Dimers and trimers are, for instance, oligomers composed of two and three monomers, respectively, such as lactose in milk for instance. However, in biochemistry, an oligomer usually refers to a macromolecular complex formed by non-covalent bonding of a few macromolecules, like nucleic acids or proteins. A clear example is those oligomers related to many neurodegenerative diseases, such as the alpha-synuclein aggregations in Parkinson’s disease.
