WGU C785 FINAL EXAM
‘What is the basic structure of an amino acid? What do they look like? (ANS-
How do you identify the 3 different types of side chains: non-polar/hydrophobic,
polar, and charged?
(ANS- Non-polar/hydrophobic
- end with CH or "can't have" water. Polar -
what kinds of bonds do each of the 3 different types of side chains
make? (ANS- ionic,
hydrophobic/non-polar,
charged
‘What are the 4 levels of protein structure?
(ANS- Primary - linear structure, Secondary - Folded into helix or pleated
‘What enviormental change breaks each type of bond?
(ANS- hydrophobic - temperature change, ionic - salt or decreased pH, hydrogen -
what type of amino acid side chain leads to protein aggregration?
(ANS- hydrophobic bonds
how do environmental changes affect protein folding?
(ANS- Extreme temp can cause hydrogen bonds to break apart = malformation of
,how do mutations affect protein structure? (ANS- _
, ‘What is an electron?
(ANS- Negatively charged atom on outer ring for bonding
What is energy:
(ANS- Power derived fro chemical interaction
what are covalent bonds?
(ANS- chemical bond, atoms share 1+ valence electrons
what is an ionic bond? (ANS- -
what is a hydrogen bond? (ANS- _
with an amino?
(ANS- piece of amino acid, NH2 or NH3
what is a carboyxl1?
(ANS- piece of amino acid, COO or COOH
‘What is hydrophobic?
(ANS- Doesn't like water, end with CH
what is hydrophilic?
(ANS- Water Lovering, end with OH, NH, or SH
what is disulfide bond?
(ANS- strongest bond between reduction agents, formed between SHs.
what are zwitterions?
(ANS- amino with positive and negative charges = overall charge of zero
