Which mineral is responsible the red colour of the blood?

Answer 1

Red BloodThe color origins from the heme-group in the hemoglobin protein, which makes up about 35% of the material of human blood and is responsible for the oxygen transport.

The heme-group is a chemical complex. A complex is a kind of chemical compound, where, in simple terms, a central particle is caged between other particles, (in the case of blood it is an iron ion or atom which is caged in a protein). They often have intense and characteristic colors, because electrons in complexes are likely to resonate with the visible spectrum of electromagnetic waves, i.e. light. They often absorb a broad spectrum of light (i.e. light of many colors), while only emitting certain part of spectrum.

In this case the heme-group emits light of the color red.

Answer 2

There is a chemical in red blood cells called hemoglobin, which has the capacity to transport oxygen. When hemoglobin has oxygen attached to it, this produces a red color.

Answer 3

hemoglobin on the red blood cells gives blood the reddish color

Answer 4

Hemoglobin
