Which elements make up fats?

Explanation:
Fats are a type of lipid built mainly from carbon, hydrogen, and oxygen. In the common form of dietary fat, triglycerides, there’s a glycerol backbone and three fatty acid chains. All of these parts are composed of carbon and hydrogen, with oxygen present in the ester bonds that link the fatty acids to glycerol. Nitrogen isn’t a feature of the basic fat molecule, and phosphorus or sulfur aren’t part of standard fats (though some related lipids, like phospholipids, include phosphorus). So the elements that make up fats are carbon, hydrogen, and oxygen.
