Amino Acid Starter Kit©
Your students will be so engaged, they won’t even notice how complex their learning is. Working collaboratively, groups of students explore the chemical properties of amino acids to guide them as they fold their own protein. Self-correcting and intuitive, this kit results. As they begin to realize that DNA is a code for amino acid sequences that ultimately determine protein structure, their confidence soars! Students will:
-
Examine patterns within and between side chains of amino acids
-
Use indicators like the colored clip at the base of each side chain indicating chemical properties and embedded colored sphere showing atomic structure
-
Organize the side chains based on chemical properties they uncover in their investigation
-
Group the side chains into one of 5 categories: hydrophobic (nonpolar), hydrophilic (polar), negatively charged, positively charged, and cysteines, which sometimes form disulfide bonds
-
Explore the primary and tertiary structure of proteins by constructing a 15-amino acid protein
-
Examine the secondary structure of proteins by folding a toober model of the first of 3 zinc fingers of the Zif268 protein
This is often referred to as the magic kit because it is astounding how the learning appears as students engage in the activities.
Improved Kit Features:
-
Modeling Ties are more durable, easy to bend, but still hold their modeled shape
-
Integrated blue and red ends on the Modeling Tie indicate directionality
-
Consistent gray color represents the carbon backbone of proteins and helps students focus on the properties of the amino acids
-
Clips grip the Modeling Tie, preventing amino acids from falling off
-
Foam bumpers adhere better to the Chemical Properties circle and don’t stretch out the clips
