WebSep 30, 2024 · Heme iron (iron bound to hemoglobin and myoglobin found in meat) can be directly absorbed by intestinal cells. This process is independent of acidity and is not affected by inhibitors of iron absorption (i.e., phytate and polyphenols) and thus, is more efficient [ 20 ]. Non-Heme Iron WebNov 22, 2024 · Typically, heme B is binded to apoprotein, a protein matrix executed with a single coordination bond between the heme iron and amino-acid side-chain. The iron contained in heme B is bounded to four nitrogens of the porphyrin and one electron donating atom of the protein, which puts it in a pentacoordinate state.
