These are convenient biochemical stereotypes. These stereotypes have … Continue reading Four types of unstable thyroid function in the elderly

Biochemical pathway maps are an important aspect of medical education and medical problem-solving. They help us to view a network or series of chemical reactions in cells. In this article, I present a comprehensive science-based pathway map showing all the major pathways of both T4 and T3 hormone metabolism, also including their urinary clearance. I … Continue reading A complete pathway map of T4 and T3 metabolism and clearance
