Well, the high concentration of hemoglobin is what gives our blood its red color. More specifically, the porphyrin functional group in the hemoglobin structure is what gives hemoglobin (and oxy-hemoglobin) its red hue.
DO NOT LET ANYONE TELL YOU THAT HEMOGLOBIN IS RED BECAUSE OF THE IRON IN THE CENTER OF ITS STRUCTURE. THEY WOULD BE LYING TO YOU.
Oxy, relaxed
It is hemoglobin that carries oxygen
Hemoglobin
because of hemoglobin
carotene, melanin, and hemoglobin
POtatos <==That is not correct, idiots!
Iron Hemoglobin which contains iron, so that it con bind oxygen. Although Iron is an element. Hemoglobin is a molecule.
The protein hemoglobin, found in the red blood cells, is what makes blood red.
The red blood cells don't loose hemoglobin. Hemoglobin is the protein the oxygen binds to. So I think a better question is " What is the colour of RBC's without oxygen?" And the answer in a dark red.
Red blood cells. They give red colour to your blood.
Blood is not always red. The colour is dependant on it's exposure to oxygen. If there is oxygen in the blood it has a red colour. That is why whenever you bleed your blood is red, because it reacts with the oxygen in the air. When there is no oxygen in your blood though, your blood has a blue colour.
1) melanin 2) carotene 3) hemoglobin
