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
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.
Blood is red because it contains hemoglobin, a protein that carries oxygen throughout the body. When hemoglobin binds to oxygen, it gives blood its red color. Essentially, the red color of blood is due to the iron in hemoglobin interacting with oxygen molecules.
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.
oxy-hydrogen
The blood color of a tiger is red. Like all mammals, tigers have red blood. The color of blood is determined by the presence of hemoglobin, which is a protein that carries oxygen. Hemoglobin is red because it contains iron.
