Konrad Bloch's investigations of the complex processes by which animal cells produce cholesterol have helped to increase our understanding of the biochemistry of living organisms. His research established the vital importance of cholesterol in animal cells and helped lay the groundwork for further research into treatment of various common diseases. For his contributions to the study of the metabolism of cholesterol, he was awarded the 1964 Nobel prize for Physiology or Medicine.
