The functional structure of a protein is its _________________ structure, which is ultimately determined by the ________________
__. A. tertiary; primary structure
B. primary; ions it possesses
C. tertiary; concentration of phosphates
D. monogamous; first amino acid on the terminal sequence
The <u>tertiary structure </u>of proteins is related to the interactions between the amino acids of the <u>primary structure</u>. Thus, these interactions give it a specific three-dimensional configuration which is very sensitive to <u>functionality</u>.
For example, <u>allosteric inhibitions</u> are related to this concept. When the <u>inhibitor</u> changes the tertiary structure of the protein it loses all <u>activity</u> and for the catalysis of the reaction.
Thus, the primary structure (which is related to the specific <u>sequence of amino acids</u>) will determine the tertiary structure since the chain folds will be a consequence of<u> intra-amino acid interactions</u>.
The tridimentional geometry of a protein is known as tertiary structure. The localization of turns inside the protein, determined by the presence of aminoacids such as Pro, Thr, Ser and Gly are examples of the influence of the primary structure in the tertiary structure of a protein. Also, the interactions between aminoacids inside the polipeptidic chain allow the protein have a specific tertiary structure.

are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. So, we calculate as follows:
Molarity = 15.9 g BaCl2 ( 1 mol / 208.23 g ) / .375 L = 0.204 mol / L</span>
