I am newly-married and I just miss the chicken, fish, and meat my mom prepares: tender and juicy and tasty. I have many cookbooks but none of them discusses this problem. We think most of your cookbooks do discuss the problem, because it has everything to do with time and temperature.
Why Blood Is Red. Human blood is red because it contains a large number of red blood cells, which contain hemoglobin. Hemoglobin is a red-colored, iron-containing protein that functions in oxygen transport by reversibly binding to oxygen. Oxygenated hemoglobin and blood are bright red; deoxygenated hemoglobin and blood are dark red.
Medical Definition of Red blood cells. Red blood cells: The blood cells that carry oxygen. Red cells contain hemoglobin and it is the hemoglobin which permits them to transport oxygen (and carbon dioxide). Hemoglobin, aside from being a transport molecule, is a pigment. It gives the cells their red color (and their name).
