Where do we get macromolecules?
We eat food composed of macromolecules, then our body breaks them down to transport through
our body, and reassembles the sub-units into macromolecules when the destination cell is reached.
What is each picture showing? Give evidence to support your claim.
A protein: we use shapes to represent the different amino acids
A chain of glucose: the hexagon mimics the chemical structure of glucose
One of these pictures shows a saturated fat, while the other shows the
amino acid lyseine. How can you figure out which is which? Give your
evidence for BOTH pictures.
The top picture shows a saturated fat: there are no double carbon
bonds and it is a chain of C, H, and O.
The picture on the right shows an amino acid. It also has a chain
of C, H, and O, but it contains nitrogen so we know it has to be a protein.
What is the difference between a glucose molecule and a monosaccharide?
A glucose molecule is a specific type of monosaccharide. A monosaccharide is a single sugar, so
it could also mean ribose (a 5-carbon sugar found in nucleic acids).
Practice your DNA bonding pairs by creating the complementary (other) strand of this double helix.

Remember, A always binds with T and C always binds with G. Look at your DNA structure notes (in your
science notebook) for a refresher.
