What is cholesterol classified as?

Cholesterol is classified as a type of fat, more specifically a lipid. It is a waxy, fat-like substance that is essential for various bodily functions. Cholesterol plays a crucial role in the formation of cell membranes, the production of hormones, and the synthesis of vitamin D and bile acids, which are important for digestion.

While carbohydrates, proteins, and vitamins are also vital macronutrients and micronutrients for the body, they serve different functions and have distinct chemical structures compared to cholesterol. Carbohydrates primarily provide energy, proteins are essential for growth and repair of tissues, and vitamins are organic compounds needed in small quantities for various biochemical processes. Cholesterol's classification as a fat helps in understanding its role in the body, as well as its relationship with health issues such as cardiovascular diseases when present in excessive amounts.
