Stearic acid (/ ˈ s t ɪər ɪ k / STEER-ik, / s t i ˈ ær ɪ k / stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain. [9] The IUPAC name is octadecanoic acid. [9] It is a soft waxy solid with the formula CH 3 (CH 2) 16 CO 2 H. [9] The triglyceride derived from three molecules of stearic acid is called stearin. [9]

In either numbering scheme, the position of a double bond in a fatty acid chain is always specified by giving the label of the carbon closest to the carboxyl end. [d] Thus, in an 18 carbon fatty acid, a double bond between C-12 (or ω−6) and C-13 (or ω−5) is said to be "at" position C-12 or ω−6. The IUPAC naming of the acid, such as ...
