Hb biochemistry - Study guides, Class notes & Summaries

These lecture notes focus on Diagnostic Biochemistry and Hematology, particularly discussing Sickle Cell Anemia and Thalassemias. It delves into the structure of hemoglobin, the synthesis of various types of hemoglobin, and how genetic defects impact the production of normal hemoglobin chains. The lecture covers the different forms of hemoglobin (Hb A, Hb F, Hb A2) present in adult blood and explains their composition. It also discusses the sequence of hemoglobin synthesis in early life, from...
