History of Wells Fargo. This article outlines the history of Wells Fargo & Company from its origins to its merger with Norwest Corporation and beyond. The new company chose to retain the name of Wells Fargo and so this article also includes the history after the merger.
Other method takes advantage of the varying conductivities of blood at. different concentrations of blood. In Hemoglobincyanide method hemoglobin is chemically converted to form a cyanmethemoglobin. which is having maximum absorption around 540nm wavelength. The hemoglobin concentration is determined.
We know that the shape of the heme group and the hemoglobin protein changes, depending on whether hemoglobin is oxygenated or deoxygenated. Therefore, these two conformations must have different light-absorbing properties. Recall that the color of a substance is the complementary color of what it absorbs. The oxygenated conformation of hemoglobin absorbs light in the blue-green range, and it reflects red light. This property accounts for the red appearance of oxygenated blood. On the other hand, the deoxygenated conformation of hemoglobin absorbs light in the orange range, and it reflects blue light.
