Web9 mrt. 2024 · Hemoglobin and myoglobin are chemically similar molecules that contain porphyrin groups. Porphyrins are cyclic structures comprised of four pyrrole rings joined by methine bridges. The arrangement of the pyrrole nitrogen atoms in the porphyrin ring allows chelation of a metal ion to form functional groups that participate in oxidative metabolism. WebEach hemoglobin is made up of 4 subunits, 2 alpha subunits, and 2 beta subunits. Each subunit surrounds the central heme group that contains iron and binds to one oxygen molecule. Hence each hemoglobin molecule can bind to four oxygen molecules. It carries oxygen from lungs to tissues. The percentage of hemoglobin in RBCs is 34%. blushing mauve revlon
