Carboceric acid

Carboceric acid, or heptacosanoic acid or heptacosylic acid, is a 27-carbon long-chain saturated fatty acid with the chemical formula. Its name derives from a combination of the word "Carbon" and κηρός (Keros), meaning beeswax or honeycomb in Ancient Greek, since the acid can be found in the mineral ozokerite, also known as ozocerite.
