Zwitterions are?
Composed of long chains of amino acids
Are scarce throughout the body
Exist because of the neutral pH of the body
ions that exist only in a basic environment
Which statement is mismatched?
The quarternary structure is related to the basic linear structure of a protein
The tertiary structure is a higher level of protein folding
The primary structure relates to the basic linear structure of a protein
The secondary structure relates to the helical shape of a protein
Which statement is true regarding enzymes?
They do not involve Van der Waal interactions
They are not always proteins
They are highly specific
They only have primary and secondary structure
Which of the following amino acids has an amide side chain?
asparagine
aspartic acid
glutamic acid
methionine
Which of the following amino acids does NOT have an aromatic ring?
tyrosine
tryptophan
histidine
proline
Which of the following is not considered part of the tertiary structure of proteins?
the hydrogen bonds
the electrostatic interactions
the restricted rotation in amide bonds
the hydrophobic effect
An enzyme changes the equilibrium constant of a reaction.
hydrophobic folding is NOT an example of secondary structure found in proteins
Amino acids are the building blocks of proteins. There are 20 amino acids used in proteins, the only amino acid that does not have a carbon atom in its side chain.
has a hydrophobic side chain characterized by four carbons that are branched in the middle
