- anabolic & catabolic reactions
- nucleic acids
Come up with a tetrapeptide (four sequences) using an amino acid from each category – non-polar, polar, negative and positive. They don’t have to be in that order or spell a word that makes sense, but could if you want them to.
Here’s the pattern to use for the task.
aa1 + aa2 –> aa1-aa2 + H2O
aa1-aa2 + aa3 –> aa1-aa2-aa3 + H2O
aa1-aa2-aa3 + aa4 –> aa1-aa2-aa3-aa4 + H2O
Use the legend below to highlight the components found in each line.
blue – amino red – carboxyl green – R group purple – peptide bond
In addition to showing them in green, identify the category that each amino acid comes from in the final tetrapeptide only.
If you want to use a different colour code that is ok but you’ll have to write out your legend for it.
