The formation of iron complexes with bile and bile constituents.
Inorganic iron is able to form complexes with whole bile and with some bile constituents and these remain soluble at neutral pH. Ascorbic acid does not appear to play a part in this process. The formation of soluble complexes in vivo is an important factor in maintaining intraluminal iron in a form available for absorption, and bile may have some importance in this respect.
