Work
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.
