Cholesterol is an organic molecule that is waxy and fat-like in texture. Cholesterol is found in all cells of the human body. It composes about 30% of all animal cells and is essential for the sustenance of life. It is not possible for animal cells to survive in the absence of cholesterol. It is by virtue of cholesterol, that the cellular membranes have fluidity. Cholesterol is needed by our bodies to synthesise Vitamin D and serves as a basis for all steroidal hormones.
