Biochemistry C785 WGU module 2
questions and explained answers
, amino group - CORRECT ANS:Consists of hydorgen and nitrogen atoms (-NH3+)
carboxyl group - CORRECT ANS:A -COOH group, found in organic acids.
R group - CORRECT ANS:a functional group that defines a particular amino acid that makes it a specific
protein (20 amino acids) aka side chain
alpha carbon - CORRECT ANS:the central carbon atom of each amino acid
amino acid backbone - CORRECT ANS:The structure comprised of the amino group, carboxyl group with
a central alpha carbon atom.
Hydrophobic - CORRECT ANS:non polar, afraid of water
polar - CORRECT ANS:Amino acid Molecule with partial charges. Mixes with water.
charged - CORRECT ANS:Amino acid has a positive or negative charge
Polypeptide - CORRECT ANS:A single protein chain formed by amino acids bonded together
peptide bond - CORRECT ANS: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 - CORRECT ANS: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)
