The Molecules of Life Collection© is a molecular model set featuring plaster models of the 4 main categories of large molecules found in all living things (biomolecules): carbohydrates, lipids, proteins and nucleic acids.
Use the Molecules of Life Placemat and the accompanying models to explore the following concepts:
Each of the structures featured is essential to sustain life.
Large biological polymers are composed of smaller building block monomers.
The biomolecules featured on the placemat and accompanying models are magnified 20 million times.
The size of atoms remains constant in all molecules. For example, oxygen (shown in red) remains the same size whether it is in a nucleotide, amino acid, starch, phospholipid or water.
Each polymer model has 1 monomer highlighted in green to help your students see the repeating pattern. For example, the DNA model has 1 nucleotide colored green and cellulose model has 1 glucose molecule colored green.
