How does fetal hemoglobin differ from adult hemoglobin?

Question

Quizplus · Accepted Answer

Fetal hemoglobin (HbF) differs from adult hemoglobin primarily in its composition of globin chains. While adult hemoglobin (HbA) consists of two alpha (α) and two beta (β) chains, fetal hemoglobin is made up of two alpha (α) and two gamma (γ) chains. This difference allows fetal hemoglobin to have a higher affinity for oxygen than adult hemoglobin, facilitating the transfer of oxygen from the mother's bloodstream to the fetus.
