Chapter 21, Problem 21A

Interpretation Introduction

Interpretation:

Protein that stores iron in the liver, spleen, and bone marrow needs to be determined.

Concept introduction:

Protein- proteins are polymer of the amino acids and they are joined together with a peptide linkage.

Iron metal is stored in the liver, spleen, and bone marrow, with the help of proteins. The proteins are as ferritin and hemosiderin.

Answer to Problem 21A

Ferritin and hemosiderin are a type of proteins which stored the iron in the liver, spleen, and bone marrow.

Explanation of Solution

Proteins are macronutrients. They are present in higher quantities in the human body. Some proteins are stored metal. Ferritin is the primary site of iron storage in the cell. The liver, spleen, and bone marrow stored iron in the form of ferritin protein and hemosiderin. The other protein that stored iron is hemoglobin, which presents in the blood.

Conclusion

The different organs stored metal as iron in the form of proteins. The proteins are named as ferritin, hemosiderin.
