The Student and Tutor worked through the detailed catalytic mechanism of an enzyme, specifically identifying the active site residues (Serine, Histidine, Aspartate) and tracing the step-by-step process of peptide bond cleavage. They focused on proton transfers, nucleophilic attacks, and the formation and breakdown of tetrahedral intermediates, ultimately demonstrating the enzyme's regeneration. The session confirmed the mechanism aligns with Chymotrypsin, a classic enzyme studied in biochemistry.

Student and Tutor reviewed topics 16 and 17, focusing on host immune system failure, immunodeficiencies, immune surveillance, autoimmunity, and the principles of vaccination. They discussed different types of immunity acquisition, various vaccine platforms, and the importance of adjuvants and boosters. The next session will involve exam preparation and practice.

The Student and Tutor completed a detailed review of the adaptive immune system, discussing the distinct roles and activation mechanisms of B and T cells, the structure and functions of various antibody classes, and the significance of MHC molecules. They analyzed how immunological memory is formed and sustained, and explored the intricate processes of immune regulation and potential dysfunctions. The next session is scheduled for November 1st.

Student and Tutor worked through several complex biochemistry problems from a worksheet, focusing on topics such as dipeptide structure and pKa determination, plotting protonation curves, optimizing protein-ligand interactions, and analyzing the thermodynamic effects of amino acid mutations on protein stability. They also discussed an ambiguous homework question that the Student plans to clarify with their instructor.

The Student and Tutor reviewed several biochemistry homework problems and exam questions, focusing on protein structure, amino acid properties, the effects of pH on protein conformation, the bicarbonate buffer system, and pKa calculations. They practiced applying concepts like Le Chatelier's Principle and the Henderson-Hasselbalch equation. They also scheduled a follow-up review session.

The Student and Tutor reviewed two comprehensive microbiology topics. First, they covered the human microbiome, discussing microbial ecology, resident communities, and the impact of antibiotics and therapies. Second, they delved into the innate immune system, exploring its barriers, cellular components, recognition mechanisms, and the processes of phagocytosis and inflammation. The Student's upcoming exams and study strategies were also briefly discussed.
