WebClearly, hemoglobin is no ordinary molecule. It is, as stated at the beginning of this article, “a giant molecule of vast complexity.” Surely, we are awed and thankful to our Creator for the brilliant and meticulous microengineering that makes life possible! [Footnote] ^ par. 12 This plate is a separate molecule called heme. WebThe interaction between hemes of the same hemoglobin molecule decreases, as shown by a drop in the value of n in Hill's equation from 2.9 to 1.5 or less. 2. In the presence of formaldehyde, both n and the oxygen pressure for half-saturation fall gradually as the pH rises in the range from pH 6.2 to 7.2. 3. Some of the effect of formaldehyde on ...
