Ferrous vs Ferric mnemonic

Ferrous vs ferric

Also, for transportation of iron I remember the fat one is 3+ and  the thin one is 2+

When you eat food, you are taking the fatty iron, that is, the 3+

For transporting it into the gut, you need to get thin, that is, get converted into 2+

Storage makes you fat. So for being stored Fe2+ is converted to Fe3+

Again, to transport it out of the gut, you need to get thin, that is, 2+

You need to be fat enough for transferring yourself to the tissues that is, 3+

Here's a diagram I made for reference -
