Complete the sentences about heme. some terms will not be used. the prosthetic group of hemoglobin and myoglobin is . the organic ring component of heme is . under normal conditions, the central atom of heme is . in , the central iron atom is displaced 0.4 å out of the plane of the porphyrin ring system. the central atom has bonds: to nitrogen atoms in the porphyrin, one to a residue, and one to oxygen.

Explanation:

Haemoglobin consists of heme unit which is comprised of an and porphyrin ring. The ring has four pyrrole molecules which are linked to the iron ion. In oxyhaemoglobin, the iron has coordinates with four nitrogen atoms and one to the F8 histidine residue and the sixth one to the oxygen. In deoxyhaemoglobin, the ion is displaced out of the ring by 0.4 Å.

The prosthetic group of hemoglobin and myoglobin is - Heme

The organic ring component of heme is - Porphyrin

Under normal conditions, the central atom of heme is -

In deoxyhemoglobin , the central iron atom is displaced 0.4 Å out of the plane of the porphyrin ring system.

The central atom has six bonds: four to nitrogen atoms in the porphyrin, one to a histidine residue, and one to oxygen.

can you list the answers so i can answer
