Zur Chemie des Blutfarbstoffes. 11. Mitteilung. Über das Hämoglobin des Menschen.

Abstract

A method for obtaining crystalline hemoglobin from human blood is described. These crystals contained 53.7% C, 7.28% H, 17% N, .37% Fe, .44% S, and 21.2% O. Blood of the new-born was more resistant to NaOH than was blood of adults. There were 2 hemoglobins in the blood of the new-born, one a very resistant kind, remnant of the fetal hemoglobin, and the other a hemoglobin like the adult compound. The labile hemoglobin was about 20%, the resistant about 80%.
