Binding capacity of haemoglobin

WebJan 5, 2024 · Total iron-binding capacity (TIBC) TIBC indicates the total amount of iron to which protein in the blood can bind. Measuring TIBC may also indicate the saturation level of iron. Hemoglobin has an oxygen-binding capacity of 1.34 mL O 2 per gram, which increases the total blood oxygen capacity seventy-fold compared to dissolved oxygen in blood. The mammalian hemoglobin molecule can bind (carry) up to four oxygen molecules.
