Carboceric acid, or heptacosanoic acid or heptacosylic acid, is a 27-carbon long-chain saturated fatty acid with the chemical formula CH
₃(CH
₂)
₂₅COOH.^[1] 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.
