Biochemistry C785 WGU module 2 Questions and
Answers 100% Correct
amino group - ANSWER Consists of hydorgen and nitrogen
atoms (-NH3+)
carboxyl group - ANSWER A -COOH group, found in organic
acids.
R group - ANSWER a functional group that defines a particular
amino acid that makes it a specific protein (20 amino acids) aka
side chain
alpha carbon - ANSWER the central carbon atom of each amino
acid
amino acid backbone - ANSWER The structure comprised of the
amino group, carboxyl group with a central alpha carbon atom.
Hydrophobic - ANSWER non polar, afraid of water
, Page |2
polar - ANSWER Amino acid Molecule with partial charges.
Mixes with water.
charged - ANSWER Amino acid has a positive or negative charge
Polypeptide - ANSWER A single protein chain formed by amino
acids bonded together
peptide bond - ANSWER The chemical bond that forms between
the carboxyl group of one amino acid and the amino group of
another amino acid by dehydration ( In which a water molecule
is removed, C-N bond)
Hydrolysis - ANSWER Peptide bonds can be broken by this...A
chemical process that splits a molecule by adding water. ( this
happened frequently in the stomach when proteins begin to
bee digested into their amino acids)
Residue - ANSWER Remaining portion of amino acids after
linked by peptide bonds ( how R groups get their name)
