Study Notes

Hemoglobin Function and Structure

Heme is responsible for binding oxygen in hemoglobin, allowing it to transport oxygen from lungs to body tissues.
Alpha chains of hemoglobin are coded by genes located on chromosome 16.

Globin Part of Hemoglobin

The primary component of the globin part of hemoglobin is globin proteins, which surround the heme group.

Porphyrias

One treatment for Porphyrias is avoiding exposure to triggers such as sunlight, certain drugs, and hormonal changes.
Most Porphyrias follow an autosomal dominant inheritance pattern, meaning a single copy of the mutated gene is enough to cause the condition.
