What is Cholesterol?
Cholesterol, also referred to as cholesterin or cholesteryl alcohol, is a complex, lipid-like molecule characterized by its waxy, fat-like nature. This organic compound belongs to the steroid family and is ubiquitously present in blood plasma and all animal tissues. It is primarily synthesized in the liver, spinal cord, and brain.
Exhibiting a white or faintly yellow appearance and almost no odor, cholesterol exists in the form of a crystalline solid. Cholesterol serves as a structural component of cell membranes, contributes to the production of hormones (such as estrogen and testosterone), and aids in the synthesis of vitamin D. While cholesterol is important for maintaining overall health, it should be present in the body in limited amounts.
Cholesterol
Cholesterol is a phospholipid present in the cells of the human body, playing a crucial role in various physiological processes. Derived from Greek words meaning bile and solid alcohol, it was first identified in gallstones in the 1770s. The cholesterol normal range in adults is typically below 200 milligrams per deciliter (mg/dL) for total cholesterol. The cholesterol formula is C27H46O.
Cholesterol is classified into two types – low-density lipoprotein (LDL) and high-density lipoprotein (HDL). While adequate levels are necessary for optimal health, an imbalance can lead to cardiovascular diseases. In this article, we will look into the meaning, cholesterol structure, and function of cholesterol along with the cholesterol properties, types, importance, and risk factors.
