Coronary Artery Disease (Ischemic Heart Disease): Overview & Coronary Artery Disease (Ischemic Heart Disease): Overview & Pathophysiology

Coronary artery disease is a condition  in which fatty deposits (atheroma) accumulate in the cells lining the wall of the coronary arteries. These fatty deposits build up gradually and irregularly in the large branches of the two main coronary arteries which encircle the heart and are the main source of its blood supply. This process…

Beer’s Law Lab Explained: Absorbance vs. Concentration

Introduction: According to Beer’s Law, A=Ebc, under ideal conditions, a substance’s concentration and its absorbance are directly proportional: a high-concentration solution absorbs more light, and solution of lower concentration absorbs less light. Since concentration and absorbance are proportional, Beer’s Law makes it possible to determine an unknown concentration of phosphate after determining the absorbance. The…
