Cholesterol is an important component in the body's cells and plays a major role in several biochemical processes. During the 1920s Adolf Windaus researched the composition of cholesterol and closely related substances, sterols. He established the sterols' relationship with bile acids. Adolf Windaus also found that ergosterol, another sterol, had the ability to cure rickets, a disease characterized by skeletal weakness and caused by a deficiency of vitamin D. He was able to show that vitamin D was formed out of ergosterol under the influence of ultraviolet light
