is the iron element in blood the same as the iron we use everyday ?

Question

There are some chemical elements in blood ,hair or in nails.of our body such as iron,zinc,cobalt...how do they related with the metalic elements we use everyday ? Are they of the same substance?

Answer 1

they are all metals, just have different atomic weights/masses and different # of valence electrons.. oxidation states.. i guess all these is what makes metals on the periodic table different from each other. You have Fe+2 in your hemoglobin/blood. Fe+3 can't find to hemoglobin.. but if you eat food that has it, it will change into fe+2 (i think) then get used by the body

Answer 2

They are infact the same element as on the periodic table however, they have are not like big chunks of iron, they are microscopic and some dissolve in your blood.

Answer 3

They are the same elements that you see on the periodic table but they are in compounds that our body can use. Not just the raw element.

Answer 4

As raw elements, yes. However the elements in our bodies seldom appear in raw form but in compounds with other elements.

Answer 5

There are now about 120 elements. Iron is iron, and cobalt is cobalt, not matter what molecule or enviornment it is in.

Answer 6

It is the same element but in a different oxidation state

Answer 7

The iron they refer to in our blood system does not relate to the iron we use everyday. From my memory in introductory biology and chemistry courses, the substances does not relate to its metallic counterparts and therefore not of the same substance.

Answer 8

yes the iron we use everyday is in a more concentrated form then type in our bodys

Answer 9

yes

Answer 10

yes.
