States
Hemoglobin is available in two conformities, for example, R state and T state.
T-State (tense)
Oxygen has less affinity to the T state than the R state. The T-state is the deoxy type of hemoglobin (implying that it comes up short on oxygen species) and is moreover known as Deoxyhemoglobin.
R-State (relaxed)
Oxygen has a greater affinity to the R state. The R-state is the oxy type of hemoglobin that is fully oxygenated and is also known as Oxyhemoglobin.
What is Hemoglobin? Definition, Structure and Function
Hemoglobin is a two-way respiratory transporter, carrying oxygen from the lungs to the tissues and working with the return carry of carbon dioxide. In the blood vessel circulation, hemoglobin has a high affinity for oxygen and a low affinity for carbon dioxide, natural phosphates, and hydrogen and chloride ions. In the venous circulation, these overall affinities are reversed.
Hemoglobin is a protein inside red blood cells that transports oxygen from the lungs to tissues and organs in the body and transports carbon dioxide back to the lungs. Testing for the level of hemoglobin count in the blood is generally a part of the Complete Blood Cell (CBC) test.
