Physical and Chemical Properties	Heme is a red blood element in the blood and muscle of higher animals. It exists in red blood cells and binds to proteins to form complex proteins, namely hemoglobin (Hb) or myoglobin (Mb). Hb is a carrier that transports O2 and a portion of CO2, and is a buffering substance that maintains a constant pH of the blood. Under certain conditions, the heme can be separated from the protein. Heme is formed by complexation of protoporphyrin IX with iron (II). Heme crystals are blue-black, insoluble in water, soluble in acidic acetone, alkaline aqueous solution, easy to form polymer in solution. There is a resonance structure in its molecule and its properties are stable. Hemin (Hemin) is black green amorphous or long needle-like crystals, insoluble in water, soluble in acidic acetone and alkaline water. The molecular formula C34H32ClFe (III) N4O4 has a molecular weight of 651.96. Mainly used for anti-anemia, anticancer drug raw materials. 1930h. Fischer (Germany) received the Nobel Prize in Chemistry for the synthesis of heme. The heme is nitrated, and the iron ion is released, and the appropriate amount of 1, 10-phenanthroline is quantitatively formed in the buffer solution of pH 4.6 to form the orange-red complex by spectrophotometry in (510±1). Determination of iron ion content in heme at nm. The results showed that the orange-red complex formed by iron ion and 1, 10-phenanthroline had the maximum absorption at the wavelength of (510±1)nm and was in the range of 0.4-2.8 μg/ml, the correlation coefficient r = 0.9999. The average recovery X = 98.87%,RSD = 0.58%.
