WebHämoglobin ist ein globuläres Protein mit sehr guter Löslichkeit in Wasser (Löslichkeit bis zu 5 mmol/l Hämoglobin (34 %)). 1 g Hb kann in vitro 1,389 ml Sauerstoff binden, in vivo jedoch nur 1,34 ml (Hüfnersche Zahl), somit können 100 ml Blut, die etwa 15 g Hb enthalten, bei 100-prozentiger Sättigung bis zu 15 × 1,34 ml = 20,1 ml Sauerstoff aufnehmen. WebOxygen transport by blood. Although oxygen dissolves in the blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen, 98.5 percent, is bound to a protein called hemoglobin and carried to the tissues. Hemoglobin, or Hb, is a protein molecule ...

WebThe solid black line shows the curve for normal adult hemoglobin (Hb A). Notable points on the curve include: p50 — The p50 is the pressure at which hemoglobin is 50% saturated (27 mmHg on the X-axis).
