CH₃(CH₂)₁₈CO₂CH₂(CH₂)₃₀CH₃

Glyceryl tripalmitate is higher melting.

$[{\mathrm{C}\mathrm{H}}_3({\mathrm{C}\mathrm{H}}_2{)}_7\mathrm{C}\mathrm{H}\text{═}\mathrm{C}\mathrm{H}({\mathrm{C}\mathrm{H}}_2{)}_7{\mathrm{C}\mathrm{O}}_2{}^{-}]2{\mathrm{M}\mathrm{g}}^{2+}$

Glyceryl dioleate monopalmitate → glycerol + 2 sodium oleate + sodium palmitate

The pro-S hydrogen is cis to the −CH₃ group; the pro-R hydrogen is trans.

Three methyl groups are removed, the side-chain double bond is reduced, and the double bond in the B ring is migrated.
