*Some cholesterol derivatives (among other simple cholesteric lipids) are known to generate the liquid crystalline "cholesteric phase". The cholesteric phase is, in fact, a chiral nematic phase, and it changes color when its temperature changes. This makes cholesterol derivatives useful for indicating temperature in liquid-crystal display thermometers and in temperature-sensitive paints.
* HP grade cholesterol can be well applied in the field of fat milk and liposome. It can achieve controlled release by encapsulating the drug/active substance in an injection and can be used as a carrier for diagnostic substances.
