Iron.
00:01
Iron is an molecule is a substance that is present in the blood and also in the tissues.
00:07
So the levels of iron which is present in the blood that is referred to be as serum and also in the tissue is regulated by two important molecule.
00:17
First one it is called as the transferin and other one it is called as the ferretin.
00:23
So these are the two important components which will regulate the levels of iron.
00:30
That is found in the serum and also in the tissue.
00:33
So this iron, as soon as it is available in the serum, it can be bound to the transferent molecule.
00:41
So as soon as it is bound to this transferent molecule, it should be noted that this transferent molecule can take up one or two ion ions.
00:49
And as soon as this is formed, this is called as the complex formation.
00:54
As soon as ion transferent ion complex forms, this in turn will be taken up.
01:00
By the receptors that is transfer in receptors which are present on the tissue or cell surface.
01:06
So as soon as they are taken in, this in turn will bind with the ferretin and it will turn help in signaling within the particular cell.
01:15
And excess of iron can also be stored in the form of ferretin in a particular cell...
