apoferritin

 [ap″o-fer´ĭ-tin]
an apoprotein that can bind many atoms of iron per molecule to form ferritin, the form in which iron is stored in the liver and other tissues.

ap·o·fer·ri·tin

(ap'ō-fer'i-tin),
A protein in the intestinal wall that combines with a ferric hydroxide-phosphate compound to form ferritin, the first stage in the absorption of iron. Apoferritin is an oligomer of 24 chains in a spheric structure; the cavity of this sphere can contain up to 4,500 Fe3+ ions.

apoferritin

A substance with which absorbed iron may be complexed in the body to form a ferritin store. Ferritin is one of the two forms of iron store in the cells of the body. The other is haemosiderin.
