Atriacylglycerol that is solid at room temperature is called a(n) fat oil lecithin cephalin wax

Triacylglycerols that are solid at room temperature are called fats.

Explanation:

Triacylglycerols is a category of lipids. Triacylglycerols are esters which are formed from three molecules of fatty acids and a glycerol molecule. Triacylglycerols are commonly known as fats and oils.

The triacylglycerols that are generally present in the solid form, at room temperature, are called fats. Whereas, the triacylglycerols that are present in the liquid form, at room temperature, are known as oils.

Therefore, triacylglycerols that are solid at room temperature are called fats.
