The __________ structure refers to the way a protein folds upon itself.
Two proteins composed of exactly the same numbers and types of amino acids, but very different sequences, may differ in
all of the above
The sequence of the amino acids in a protein determines the tertiary structure. The secondary structure of the protein is determined the sequence. Biologic activity of proteins is determined by the R groups available for reactions and the shape of the protein. A change in the shape of a protein can either restrict protein activity or change protein activity.
Disulfide bridges form between
Which of the following types of covalent bonds contributes to the tertiary structure of a protein?
Which of the following amino acids would most likely be found in the interior of a globular protein that exists in the cytosol of a cell?
What part do Van der Waals forces play in the tertiary structure of a protein?
they are involved in attraction between nonpolar R groups in the protein interior
• Several major interactions take place between R groups:
: hydrophobic interactions, Van der Waals interactions,
ionic bonding, and formation of disulfide bridges.
Four main types of interactions give a polypeptide its
Hydrogen Bonds may also participate in stabilizing
the tertiary structure
_______ are strong covalent bonds that
form between two cysteine molecules.
