True or false?
Blood is red because of the iron in hemoglobin.
“Red blood cells”
A close-up of red blood
cells within a capillary.
Over 99 percent
of the blood vessels in the body
are capillaries,
even though they only hold 5
percent of the body’s blood.
False
por·phy·rin
Function: noun
Etymology: from Greek porphyra purple
-any of various compounds with a macrocyclic structure that consists essentially of four
pyrrole rings joined by four =CH- groups; especially : one (as chlorophyll or hemoglobin)
containing a central metal atom and usually exhibiting biological activity
Nature’s synthesis of Porphyrin
the pyrrole ring is formed
