Biochemistry - C785 Module 2
carboxyl group Correct Answer: A -COOH group, found in organic acids.
amino group Correct Answer: a chemical group consisting of a nitrogen atom bonded to two hydrogen atoms
Where are the hydrophobic amino acids found in the protein? Correct Answer: found in the interior of the protein
What kind of bond connects a positively charged group and a negatively charged group? Correct Answer: ionic bond
What type of reaction forms a peptide bond? Correct Answer: dehydration synthesis
What type of reactions breaks the peptide bond? Correct Answer: Hydrolysis reaction
Peptide bonds are in what structure? Correct Answer: Primary structure
Hydrogen bonds hold which structure together? Correct Answer: Secondary and tertiary
What amino acids are found on the exterior of the protein? Correct Answer: polar amino acids
Two non-polar amino acids make what kind of interaction? Correct Answer: Hydrophobic interactions
Non-covalent interactions between amino acid R groups Correct Answer: hydrophobic, ionic and hydrogen bonds
What structure has a disulfide bond that holds together 2 subunits of an enzyme? Correct Answer: quaternary structure
What structure has an Ionic interactions that hold together 4 different subunits of a protein? Correct Answer: quaternary structure
What structure has an Ionic interactions that hold together 3 identical polypeptides Correct Answer: quaternary structure
non polar amino acids Correct Answer: hydrophobic bond, weak strength, heat disrupts the interaction
primary structure of protein Correct Answer: the amino acid sequence of the polypeptide chain
secondary structure of protein Correct Answer: Hydrogen bonds are involved in this level of structure and the amino and carboxyl groups (backbone) form these bonds
tertiary structure of protein Correct Answer: hydrogen, ionic and disulfide bonds as well as hydrophobic interactions
quaternary structure of a protein Correct Answer: 2 or more polypeptides interact to form the protein
Fate of misfolded proteins Correct Answer: aggregation, degradation and refolding
