Then, at minutes 27:34 and 28:10, pKa2 was also corrected to pKa3. This is incorrect and shouldn't have been corrected because the information in the equilibrium reaction is correct and not interchangeable. Here's the explanation: The constant for amino acids is that pKa1 is the acidity constant for the carboxyl group no. 1, pKa2 for the alpha-ammonium group, and pKa3 for the acidic group in the side chain. As a reference, the pKa1, pKa2, and pKa3 values ​​in the table at minutes 35:00 to 36:30 are correct. So, the rules differ from those we know in Basic Chemistry, where pKa1, pKa2, and pKa3 are ordered from the most acidic proton to the least acidic proton. At 47:03 to 47:08, it says, "Then myoglobin will carry it throughout the body through the blood." It should be, "Then hemoglobin will also carry it throughout the body through the blood. Myoglobin in cellular tissue will then bind oxygen from the blood." The correction has been submitted. Thank you.
