When BHBA is consumed in the drink HVMN Ketone Ester it eventually passes into the bloodstream. Blood is buffered at a pH of 7.4. Calculate the ratio of conjugate base to conjugate acid for BHBA in the blood stream. Which is the principal chemical form in the bloodstream, the conjugate acid or the conjugate base? C.

Question
Part c
![beta-Hydroxybutyric acid (BHBA) is an interesting molecule that is constantly circulating in your bloodstream. BHBA becomes elevated when your metabolism is driven into ketosis, a state that occurs when carbohydrates and glycogen are no longer available for metabolism and your body turns to using fats instead. Some athletes believe that forcing themselves into ketosis before a competition increases performance and products such as the drink HVMN Ketone Ester have been developed for this purpose. The structure of BHBA is shown below:

a. Draw the structures of the conjugate acid and conjugate base forms of BHBA.
b. Calculate the pH of a solution that contains 0.0353 mole of BHBA in 500 mL of water given that the pKa of BHBA is 4.70. Which is the principal chemical form of BHBA in aqueous solution, the conjugate acid or the conjugate base?
