Correct Answers
What is the basic structure of an amino acid? What do they look like? -
hydrophobic - temperature change, ionic - salt or decreased pH, hydrogen -
correct
answer amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon
(C), and variable group
How do you identify the 3 different types of side chains: non-polar/hydrophobic,
polar, and charged?
- correct answer Non-polar/hydrophobic - end with CH or "can't
have" water. Polar - end with OH, SH, or NH. Charged - end with a charge
what kinds of bonds do each of the 3 different types of side chains make? -
correct
answer ionic, hydrophobic/non-polar, charged
What are the 4 levels of protein structure? -
structure, Secondary - Folded into helix or pleated sheet caused by hydrogen
correct answer Primary - linear
bonding, tertiary - 3D structure caused by side chain interactions, quaternary - 1+
amino acid chains combine = multiple subunits MUST have 1+ subunit
What enviormental change breaks each type of bond? -
correct answer
temperature, change in pH, disulfide - reducing agents
what type of amino acid side chain leads to protein aggregration? -
hydrophobic bonds
correct answer

how do environmental changes affect protein folding?
- correct answer Extreme
temp can cause hydrogen bonds to break apart = malformation of protein folding
how do mutations affect protein structure? -
correct answer Can cause structure to
change. Protein loses form = loses function. May form a different protein.
