CORRECT VERIFIED ANSWERS

ACTUAL UPDATE(A+)
What is the basic structure of an amino acid? What do they look like? -CORRECT
ANS>>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 ANS>>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 ANS>>ionic, hydrophobic/non-polar, charged
What are the 4 levels of protein structure?
-CORRECT ANS>>Primary - linear structure, Secondary - Folded into helix or
pleated sheet caused by hydrogen 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 ANS>>hydrophobic - temperature change, ionic - salt or decreased
pH, hydrogen - temperature, change in pH, disulfide - reducing agents
what type of amino acid side chain leads to protein aggregration? -CORRECT
ANS>>hydrophobic bonds
how do environmental changes affect protein folding?
-CORRECT ANS>>Extreme temp can cause hydrogen bonds to break apart =
malformation of protein folding
how do mutations affect protein structure? -CORRECT ANS>>Can cause
,structure to change. Protein loses form = loses function. May form a different
protein.
, What is an electron?
-CORRECT ANS>>Negatively charged atom on outer ring for bonding
What is energy:
-CORRECT ANS>>Power derived fro chemical interaction
what are covalent bonds?
-CORRECT ANS>>chemical bond, atoms share 1+ valence electrons
what is an ionic bond? -CORRECT ANS>>bond between positive and negative
what is a hydrogen bond? -CORRECT ANS>>weak bond between positive and
negative
with an amino?
-CORRECT ANS>>piece of amino acid, NH2 or NH3
what is a carboyxl?
-CORRECT ANS>>piece of amino acid, COO or COOH
What is hydrophobic?
-CORRECT ANS>>Doesn't like water, end with CH
what is hydrophilic?
-CORRECT ANS>>Water Lovering, end with OH, NH, or SH
what is disulfide bond?
-CORRECT ANS>>strongest bond between reduction agents, formed between
SH's.
what are zwitterions?
-CORRECT ANS>>amino with positive and negative charges = overall charge of
zero
