Prize share: 1/2
In addition to carbohydrates, proteins and fats, our bodies need vitamins to function well. Henrik Dam's revelation that a substance he called vitamin K was needed for blood to coagulate was followed by a number of investigations into how this substance can be obtained. In 1939 Edward Doisy succeeded in producing two variants of vitamin K in pure form, allowing him to determine its structure and to produce it by artificial means. This became especially important in treating bleeding among small children.
Their work and discoveries range from the Earth’s climate and our sense of touch to efforts to safeguard freedom of expression.
