1. Introduction - 0:00
The session starts with a greeting to participants and a brief overview of the session's topics.

2. Ka and pKa Relationship (Strengths of Acids) - 0:10
We begin by exploring the relationship between Ka and pKa to understand acid strength. This foundational concept is crucial for interpreting acid-base behavior and reaction mechanisms in organic and biochemistry.

3. Carbonic Acid-Bicarbonate Buffer System - 9:02
This section covers the carbonic acid-bicarbonate buffer system, a key physiological buffer that regulates blood pH. Understanding buffer systems is essential for students interested in biochemistry, physiology, and medical studies.

4. Physicochemical Properties of Amino Acids/General Structure of Amino Acids - 20:35
Here, I discuss the general structure of amino acids and their physicochemical properties. Grasping amino acid characteristics is vital for studying protein structure, function, and enzyme catalysis in biochemistry.

5. Determining What Charge a Group Will Have at a Certain pH Based on Their pKa - 23:37
We explore how to determine the charge of amino acid groups at various pH levels based on their pKa values. This skill is key for understanding amino acid behavior in proteins and enzyme active sites.

6. Surprise Hello from Alex! :D - 47:58
A special guest appearance from Alex brings a fun surprise to the session! Enjoy a quick break as we catch up and share some light-hearted moments.

7. Range of pH Where the Side Chain of Tyrosine is Fully Deprotonated or Protonated - 1:02:54
In this final segment, we discuss the specific pH range where the side chain of tyrosine is fully deprotonated or protonated. This topic is essential for understanding amino acid reactivity and enzyme functionality in varying pH environments.
