The analytical concentration of lactic acid in blood is generally less than 1.20 x 10^-⁴ M, corresponding to the sum of [lactate] and [lactic acid]. During strenuous exercise, however, oxygen in the muscle tissue is depleted, and overproduction of lactic acid occurs. This leads to a condition known as lactic acidosis, which is characterized by elevated blood lactic acid levels (approximately 5.00 x 10^-3 M). The pK_a of lactic acid is 3.9.

1. What is the actual lactic acid concentration under normal physiological conditions?

2. what is the actual lactic acid concentration during lactic acid acidosis?

you can use your own examples.

A solution containing a mixture of lactic acid and lactate was found to have a pH of 3.56. Calculate the ratio of the lactate concentration to the lactic acid concentration in this solution.

During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of glucose is converted into lactate. High lactate levels can lead to acidity in the muscle cells as some of the lactate hydrolyzes to lactic acid. The dissociation of lactic acid to lactate is shown in the reaction below. Lactic acid has a pKa of 3.86. A solution containing a mixture of lactic acid and lactate was found to...

What determines the taste of cheddar cheese? Experimenters assessed the concentration of lactic acid, acetic acid, and hydrogen sulfide in randomly chosen pieces of cheddar cheese that were also rated for taste by a panel of food tasters (the higher the score, the tastier). Data from the study are shown in the provided table, “Acetic” and are actually log‑transformed concentrations.
