Ernst Felix (Immanuel) Hoppe-Seyler was a German physician, who was a pioneer of physiological chemistry (biochemistry). He studied the chemical of blood and urine using the new technique of absorption spectroscopy, prepared hemoglobin in crystalline form and clarified its role in red blood cells. He demonstrated that the oxidation reactions between haemoglobin, oxygen and carbon monoxide took place in the tissues rather than in the blood itself. He also studied chlorophyll and was the first to prepare lecithin in a pure form. He coined the word proteid, now replaced with the word protein. He also investigated bile acids, lipid metabolism, quantification and classification of proteins and inspired research on nucleic acids.
