Iron Absorption, Transport, Metabolism and Regulation - Biochemistry Lesson

The video explains iron absorption, transport, and metabolism in the body. It covers how iron is absorbed in the intestines, stored, and transported in the bloodstream. The role of proteins like duodenal cytochrome B, ferritin, and transferrin is discussed, along with the regulation of iron levels by hepcidin. The video also outlines dietary sources of iron, recommended daily allowances for different age groups, and the increased needs during pregnancy.
