Lipids are non-polar molecules and are hydrophobic, meaning that they do not mix well with water. The fact that the liquid separated into two layers when mixed with water suggests that it is a lipid. The other classes of biological molecules - carbohydrates, proteins, enzymes, and nucleic acids - are all polar and hydrophilic, meaning that they mix well with water and would not separate into layers.
