Question

why iron present in food is not in solid form

Answer 1

No, they are as different as oxygen that you breathe and oxygen in water that you drink.

First: Iron is not a molecular compound, so you can not speak about iron molecules. Metals like iron (as a block) are present in atomic form, with some of the outer electrons buzzing around.

In the body, iron is present as ions that are coordinated in different ways, most commonly known in so-called heme groups in proteins like haemoglobin
