cholesterol
UK: kəˈlɛstərɒl | US: kəˈlɛstəˌroʊl
n. a sterol (fat-like substance) found in animal tissues, blood, and food, essential for cell membranes but harmful in excess.
The word "cholesterol" originates from Greek and scientific Latin. "Chole" (Greek: χολή) means "bile," as cholesterol was first isolated from gallstones. "Ster" derives from Greek "stereos" (solid), referring to its waxy, fat-like consistency. The suffix "-ol" indicates it is an alcohol chemically. The term reflects its discovery context and molecular structure—a rigid, bile-derived alcohol.
