Wieland, Heinrich Otto (1877–1957) German chemist. Wieland received the 1927 Nobel Prize in chemistry for his research into bile acids. He showed them to have a steroid skeleton, and thus found that they were structurally related to cholesterol. He also did research into oxidation reactions occurring in living tissues and discovered that they involved the removal of hydrogen, not the addition of oxygen.
