WGU C785 Final Exam 2026 With All The
Correct Answers
Amino acid - ,,,,,,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 - ,,,,,,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 - ,,,,,,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) - ,,,,,,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.
