In mammals, hemoglobin makes up about 96% of a red blood cell's dry weight (excluding water), and around 35% of the total weight (including water). [5] Hemoglobin has an oxygen-binding capacity of 1.34 mL of O 2 per gram, [ 6 ] which increases the total blood oxygen capacity seventy-fold compared to dissolved oxygen in blood plasma alone. [ 7 ]
