A supply of oxygen is a prerequisite for metabolism in our bodies' cells. Oxygen is transported by the blood, and in particular by hemoglobin, a substance that gives blood its red color. Hemoglobin is composed of the protein globin and what is called the hem group. Hans Fischer mapped the composition of the hem group and in 1929 succeeded in producing the substance by artificial means. He also studied other pigmented substances of biological importance, including chlorophyll, which plays a crucial role in plant photosynthesis.
