Questions and CORRECT Answers
Amino acid - CORRECT ANSWER - Building blocks of proteins.
Amino group + Carboxylic acid + R group = Amino acid


Nitrogen with at least
one Hydrogen attached
Can be NH2 or NH3+


Carbon that sits
between amino
and carboxyl.
Hydrogen "hat"


Carbon with two
attached oxygens
Can be COOH or COO-


Amino Acid Structure - CORRECT ANSWER - Consist of a Backbone side chain/R group
Carboxyl group: Carbon with two attached oxygens
Can be COOH or COO-
Amino Group: Nitrogen with at least one Hydrogen attached Can be NH2 or NH3+
Alfa Carbon (a carbon): Carbon that sits between amino
and carboxyl Hydrogen "hat"


Side chain/R group: consists of...
Varible group: Unique portion of the

, amino acid.


Amino Acid types - CORRECT ANSWER - Are identified by the R (variable)group.
Hydrophobic: no charge, no S, N, or O
Polar: no charge, must contain a S,N, or O
Charged: Have a Charge


Ionic Bonds (Charged amino acids) - CORRECT ANSWER - Two charged amino acids
form a iconc bond.
Bond disrupted by: pH or Salt concentration


Charged amino acids form ionic bonds with other
oppositely charged amino acids.
Other charges like H+ from pH or salts (charged
particles) break up these bonds.


Hydrogen Bonds (Polar amino acids) - CORRECT ANSWER - Two polar amino acids
form hydrogen bonds
Bond disrupted by: pH or Salt concentration


Polar forms hydrogen bonds with other polar.
Cysteine forms disulfide bonds with other Cysteine.
Hydrogen bonds broken by ions like H+ or salt.
Disulfide bonds broken by reducing agents


Hydrophobic ( non polar amino acids) - CORRECT ANSWER - A bond between two non
polar amino acids


Nonpolar amino acids form hydrophobic
